# cwc-website: Development Specification

## What is cwc-website?

The public-facing website for codingwithclaude.dev - a developer publishing platform where users can share technical blog posts organized by Projects.

---

## MVP Goals

Launch a read-only, SEO-ready site as quickly as possible:

1. **Landing page** - Introduce codingwithclaude.dev, link to the coding-with-claude project
2. **Project content** - Display the coding-with-claude project and its coding sessions
3. **SEO-ready** - Server-side rendering for search engine indexing
4. **Static pages** - About, Privacy Policy

**Not in MVP:** Authentication, user interactions (comments, reactions), create/edit functionality

---

## User Roles

- **guest-user**: Not logged in, read-only access to published content
- **logged-on-user**: Can view, react, comment, and create projects
- **project-owner**: Can edit and delete their own projects

---

## MVP Pages

| Page           | URL                                | Description                  |
| -------------- | ---------------------------------- | ---------------------------- |
| Home           | `/`                                | Landing page with site intro |
| About          | `/about`                           | About the platform           |
| Privacy Policy | `/privacy-policy`                  | Privacy policy               |
| Project List   | `/projects`                        | List of all projects         |
| Project        | `/project/:projectId`              | Single project detail        |
| Coding Session | `/project/:projectId/sessions/:id` | Single coding session        |

---

## Future Pages (Post-MVP)

- Logon, Logout, Signup, PasswordReset
- UserProfile, UserProfileEdit
- ProjectCreate, ProjectEdit
- CodingSessionImport

---

## Technology Stack

- **React 19** - UI library
- **React Router v7** - Framework mode with SSR
- **Vite** - Build tool
- **SCSS** - Styling (colocated with layout templates)

---

## Configuration (cwc-configuration-helper)

**Config type file:** `packages/cwc-website/src/config/config.types.ts`

```typescript
export type CwcWebsiteConfig = {
  appUrl: string; // Public URL of the website
  apiUri: string; // cwc-api service URL
  contentUri: string; // cwc-content service URL
};
```

**Environment variables:**

| Variable      | Example Value                      |
| ------------- | ---------------------------------- |
| `APP_URL`     | `https://codingwithclaude.dev`     |
| `API_URI`     | `http://cwc-api:5040/api/v1`       |
| `CONTENT_URI` | `http://cwc-content:5008/content/v1` |

---

## Deployment Changes (cwc-deployment)

**Key difference:** React Router v7 with SSR requires a Node.js server (not static files).

**Changes needed in cwc-deployment:**

1. Add `cwc-website` as a deployable service type
2. Dockerfile pattern similar to backend services (Node.js runtime)
3. nginx configuration already routes to cwc-website (from Phase 0 of Next.js work)

**Build vs Runtime:**

- Next.js: Environment variables baked in at build time
- React Router v7: Environment variables can be read at runtime (more flexible)

```

**Note:** Files at `src/` root (`entry.client.tsx`, `entry.server.tsx`, `root.tsx`, `routes.ts`) follow React Router v7 framework conventions and cannot be renamed or relocated.

**CRITICAL:** Route modules (including layouts) must have a **default export** for React Router v7 to use them.

---

## Data Fetching Strategy

- **Project/CodingSession metadata**: Fetch from cwc-api service
- **CodingSession content**: Fetch from cwc-content service
- **For now**: Use mocks with comments indicating where real API calls will go
- **Caching**: None for MVP - loaders fetch fresh data, rely on HTTP caching at API level

---

## Manual Setup Tasks (Pre-Launch)

Before the MVP can go live, these tasks need to be done manually or via utilities:

1. Create user "jeff" in the database - **Use `pnpm admin-util exec generate-user`**
2. Setup the "coding-with-claude" project in the database - **Use `pnpm admin-util exec generate-project`**
3. Import coding sessions using cwc-transcript-parser

---

# CWC Deployment Cheatsheet

All scripts use default paths:

- Secrets: `~/cwc/private/cwc-secrets`
- Builds: `~/cwc/private/cwc-builds`
- Certs (local): `~/cwc/private/cwc-certs`

---

## Docker Compose Deployment (Recommended)

Deploys all services together with automatic DNS-based service discovery.

### Deploy Full Stack

```bash
# Deploy test environment (all services)
./deployment-scripts/deploy-compose.sh test

# Deploy with database schema initialization
./deployment-scripts/deploy-compose.sh test --create-schema

# Deploy production
./deployment-scripts/deploy-compose.sh prod
```

### Deploy With Database

By default, database is excluded to protect data. Use these flags to include it:

```bash
# Include database in deployment (no schema changes)
./deployment-scripts/deploy-compose.sh test --with-database

# Include database with schema initialization (first-time setup)
./deployment-scripts/deploy-compose.sh test --create-schema
```

Note: `--create-schema` implies `--with-database`.

### Undeploy Compose Stack

```bash
# Undeploy and remove all data
./deployment-scripts/undeploy-compose.sh test

# Undeploy but keep database and storage data
./deployment-scripts/undeploy-compose.sh test --keep-data
```

### SSL Certificate Management

Certificates are automatically checked/renewed during deploy-compose.sh.
To manually renew or force renewal:

```bash
# Check and renew if expiring within 30 days
./deployment-scripts/renew-certs.sh test

# Force renewal regardless of expiry
./deployment-scripts/renew-certs.sh test --force

# Test with Let's Encrypt staging server (avoids rate limits)
# Staging certs are saved separately and won't overwrite production certs
./deployment-scripts/renew-certs.sh test --staging

# Dry-run to test the process without generating certs
./deployment-scripts/renew-certs.sh test --dry-run

# Combine flags
./deployment-scripts/renew-certs.sh test --staging --force
```

**Staging vs Production:**

- Staging certs: `~/cwc-certs-staging/` (local), `/home/devops/cwc-certs-staging/` (server)
- Production certs: `~/cwc-certs/` (local), `/home/devops/cwc-certs/` (server)
- Staging certs are NOT trusted by browsers - for testing cert generation only

Prerequisites for cert renewal:

- `certbot` installed locally
- `certbot-dns-digitalocean` plugin installed (`pip install certbot-dns-digitalocean`)
- DigitalOcean API token at `~/cwc/private/cwc-secrets/dns/digitalocean.ini`

---

## Individual Service Deployment (Legacy)

For deploying services individually without Docker Compose.

### Deploy Database

```bash
./deployment-scripts/deploy-db.sh test
```

## Deploy All Services

Deploys in dependency order: sql → auth → storage → content → api

```bash
./deployment-scripts/deploy-all-services.sh test
```

## Deploy Individual Services

```bash
./deployment-scripts/deploy-sql.sh test
./deployment-scripts/deploy-auth.sh test
./deployment-scripts/deploy-storage.sh test
./deployment-scripts/deploy-content.sh test
./deployment-scripts/deploy-api.sh test
```

## Undeploy All Services

Undeploys in reverse order: api → content → storage → auth → sql

```bash
./deployment-scripts/undeploy-all-services.sh test 2025-01-15-143022
```

## Undeploy Individual Services

```bash
./deployment-scripts/undeploy-sql.sh test 2025-01-15-143022
./deployment-scripts/undeploy-auth.sh test 2025-01-15-143022
./deployment-scripts/undeploy-storage.sh test 2025-01-15-143022
./deployment-scripts/undeploy-content.sh test 2025-01-15-143022
./deployment-scripts/undeploy-api.sh test 2025-01-15-143022
```

## Undeploy Database

```bash
./deployment-scripts/undeploy-db.sh test 2025-01-15-143022
```

## Redeploy Database

```bash
./deployment-scripts/redeploy-db.sh test 2025-01-15-143022
```

## List Deployments

```bash
./deployment-scripts/list-deployments.sh test
./deployment-scripts/list-deployments.sh test database
```

## Diagnose Database Issues

```bash
./deployment-scripts/diagnose-db.sh test
```

# cwc-deployment

Custom TypeScript/Node.js deployment CLI for SSH-based deployment of CWC services to remote servers.

## Overview

`cwc-deployment` is a custom deployment tool that:
- Runs from your local development machine
- Connects to remote servers via SSH (passwordless key authentication)
- Builds deployment archives with all necessary files
- Transfers archives to server and executes deployment via Docker
- Supports deploy, redeploy, undeploy, and list commands
- Provides comprehensive validation before deployment

**Deployed as Docker containers:**
- Database: MariaDB 11.8
- Microservices: Node.js containers (future)
- Web apps: nginx + static files (future)

## Prerequisites

- Node.js 22 LTS
- pnpm 9.x
- SSH access to target deployment server
- Docker installed and running on target server
- SSH key for passwordless authentication

## Installation

From the monorepo root:

```bash
# Install dependencies
pnpm install

# Build the deployment tool
pnpm --filter cwc-deployment build
```

## Configuration

### 1. Create Secrets Directory Structure

Create a secrets directory outside the monorepo (e.g., `~/cwc-secrets`):

```bash
mkdir -p ~/cwc-secrets/configuration-helper
mkdir -p ~/cwc-secrets/deployment/ssh-keys
```

### 2. Create Environment Secrets Files

Database secrets are stored in configuration-helper secrets files, one per deployment environment.

Create `~/cwc-secrets/configuration-helper/{deploymentName}-secrets.json` for each environment (e.g., `dev-secrets.json`, `test-secrets.json`, `prod-secrets.json`):

```json
{
  "DATABASE_ROOT_PASSWORD": "your-root-password",
  "DATABASE_USER": "your-mariadb-username",
  "DATABASE_PASSWORD": "your-mariadb-password",
  "SQL_CLIENT_API_KEY": "-----BEGIN PUBLIC KEY-----\n...",
  "USER_JWT_SECRET": "your-jwt-secret",
  "TEMP_JWT_SECRET": "your-temp-jwt-secret"
}
```

**Note:** This consolidated secrets file is used by both cwc-deployment (for database deployment) and cwc-configuration-helper (for generating .env files).

### 3. Create Servers Configuration

Create `~/cwc-secrets/deployment/servers.json`:

```json
{
  "dev": {
    "host": "dev.example.com",
    "username": "deploy-user",
    "sshKeyPath": "~/cwc-secrets/deployment/ssh-keys/dev-server-key",
    "basePath": "/home/deploy-user"
  },
  "test": {
    "host": "test.example.com",
    "username": "deploy-user",
    "sshKeyPath": "~/cwc-secrets/deployment/ssh-keys/test-server-key",
    "basePath": "/home/deploy-user"
  },
  "prod": {
    "host": "prod.example.com",
    "username": "deploy-user",
    "sshKeyPath": "~/cwc-secrets/deployment/ssh-keys/prod-server-key",
    "basePath": "/home/deploy-user"
  }
}
```

### 4. Add SSH Keys

Copy your SSH private keys to `~/cwc-secrets/deployment/ssh-keys/`:

```bash
cp ~/.ssh/dev-server-key ~/cwc-secrets/deployment/ssh-keys/
chmod 600 ~/cwc-secrets/deployment/ssh-keys/*
```

### 5. Create Builds Directory

```bash
mkdir -p ~/cwc-builds
```

## Usage

### Deploy Database (Shell Script)

Deploy a fresh database instance using the shell script wrapper:

```bash
./deployment-scripts/deploy-db.sh \
  --server test \
  --deployment-name test \
  --secrets-path ~/cwc-secrets \
  --builds-path ~/cwc-builds \
  --create-schema
```

**Options:**
- `--create-schema` - Include SQL initialization scripts (use for first deployment)
- `--port <number>` - External port mapping (default: auto-calculated from deployment name)

**What happens:**
1. **Validation:** SSH connectivity, Docker availability, configuration
2. **Cleanup:** Removes existing containers/images matching pattern
3. **Build:** Creates deployment archive with Dockerfile and init scripts
4. **Transfer:** SCPs archive to server
5. **Deploy:** Creates Docker network, builds image, runs container
6. **Verify:** Tests database connectivity and schema creation

**Build structure:**
```
~/cwc-builds/
└── test/
    └── cwc-database/
        └── 2025-11-18-195147/
            ├── deploy/
            │   ├── Dockerfile
            │   ├── mariadb.cnf
            │   └── init-scripts/
            │       ├── 00-create-schema.sql
            │       ├── 01-create-tables.sql
            │       ├── 02-create-indexes.sql
            │       └── 03-create-views.sql
            └── cwc-database-test-2025-11-18-195147.tar.gz
```

**Server structure:**
```
/home/user/
├── deployment/
│   └── test/
│       └── cwc-database/
│           └── 2025-11-18-195147/
│               ├── Dockerfile
│               ├── mariadb.cnf
│               └── init-scripts/
└── test-cwc-database/
    └── data/  # Persistent database files
```

### Redeploy Database (Shell Script)

Redeploy with a new timestamp (keeps data, removes old container/image):

```bash
./deployment-scripts/redeploy-db.sh \
  --server test \
  --deployment-name test \
  --secrets-path ~/cwc-secrets \
  --builds-path ~/cwc-builds
```

**What happens:**
- **Note:** Redeploy is just an alias to deploy (automatic cleanup makes them equivalent)
- Performs same steps as deploy command
- **Keeps data directory** (preserves database)
- New container mounts existing data (no re-initialization unless `--create-schema` provided)

### Undeploy Database (Shell Script)

Remove a specific deployment:

```bash
./deployment-scripts/undeploy-db.sh \
  --server test \
  --deployment-name test \
  --timestamp 2025-11-18-195147 \
  --secrets-path ~/cwc-secrets
```

**Options:**
- `--keep-data` - Preserve data directory
- `--keep-files` - Preserve deployment files on server

**What happens:**
1. Stops container
2. Removes container
3. Removes image
4. Removes network (if not in use by other containers)
5. Removes data directory (unless `--keep-data`)
6. Removes deployment files (unless `--keep-files`)

### List Deployments (Shell Script)

List all CWC deployments on a server:

```bash
./deployment-scripts/list-deployments.sh \
  --server test \
  --secrets-path ~/cwc-secrets
```

**Filter by deployment name:**
```bash
./deployment-scripts/list-deployments.sh \
  --server test \
  --secrets-path ~/cwc-secrets \
  --deployment-name test
```

**Filter by service:**
```bash
./deployment-scripts/list-deployments.sh \
  --server test \
  --secrets-path ~/cwc-secrets \
  --service database
```

## Advanced Usage

### Multiple Isolated Deployments

Deploy different versions side-by-side:

```bash
# Main test deployment
./deployment-scripts/deploy-db.sh \
  --server test \
  --deployment-name test \
  --secrets-path ~/cwc-secrets \
  --builds-path ~/cwc-builds

# Feature branch deployment
./deployment-scripts/deploy-db.sh \
  --server test \
  --deployment-name test-feature-auth \
  --secrets-path ~/cwc-secrets \
  --builds-path ~/cwc-builds

# Old release for comparison
./deployment-scripts/deploy-db.sh \
  --server test \
  --deployment-name test-release-1-5-6 \
  --secrets-path ~/cwc-secrets \
  --builds-path ~/cwc-builds
```

Each deployment gets:
- Unique Docker network: `cwc-test`, `cwc-test-feature-auth`, `cwc-test-release-1-5-6`
- Unique data directory: `/home/user/test-cwc-database/`, `/home/user/test-feature-auth-cwc-database/`, etc.
- Unique containers and images with timestamps

## Architecture

### Naming Conventions

**Timestamp Format:** `YYYY-MM-DD-HHMMSS` (hyphenated for readability)
- Example: `2025-11-18-195147`

**Docker Resources:**
- **Docker Image:** `{serviceName}:{deploymentName}-{timestamp}`
  - Example: `cwc-database:test-2025-11-18-195147`
- **Docker Container:** `{serviceName}-{deploymentName}-{timestamp}`
  - Example: `cwc-database-test-2025-11-18-195147`
- **Docker Network:** `cwc-{deploymentName}`
  - Example: `cwc-test` (shared across all timestamps for same deployment)
- **Archive:** `{serviceName}-{deploymentName}-{timestamp}.tar.gz`
  - Example: `cwc-database-test-2025-11-18-195147.tar.gz`

### Directory Structure

**Build Path:** `{buildsPath}/{deploymentName}/{serviceName}/{timestamp}/`

**Server Deployment Path:** `{basePath}/deployment/{deploymentName}/{serviceName}/{timestamp}/`

**Server Data Path:** `{basePath}/{deploymentName}-{serviceName}/data/`

**Critical:** Data path includes service name to prevent conflicts with other database instances

### Network Configuration

Docker networks use calculated subnets to avoid conflicts:

- Network name: `cwc-{deploymentName}`
- Subnet: `192.1.{N}.0/24` (N calculated from deployment name hash, 1-254)
- Container IP: `192.1.{N}.2`

Example:
- `cwc-test` → `192.1.2.0/24` → container at `192.1.2.2`
- `cwc-prod` → `192.1.3.0/24` → container at `192.1.3.2`

### MariaDB Auto-Initialization

Files in `init-scripts/` are automatically executed by MariaDB **only on first initialization** when the data directory is empty:

1. `00-create-schema.sql` - Creates `cwc` schema
2. `01-create-tables.sql` - Creates all database tables
3. `02-create-indexes.sql` - Creates all indexes
4. `03-create-views.sql` - Creates all views

Scripts run in alphabetical order, so numbering ensures correct execution sequence.

**Important:** Scripts only run when data directory is empty. If data exists, MariaDB skips initialization.

## Validation Checks

Before each deployment, the tool validates:

1. ✅ Secrets path exists and is accessible
2. ✅ Builds path exists (creates if missing)
3. ✅ SSH key file exists and has correct permissions
4. ✅ SSH connection successful to target server
5. ✅ Docker installed and running on server
6. ✅ Deployment conflicts detected (warns if redeploying)

## Troubleshooting

### SSH Connection Fails

**Error:** `Failed to connect to server: Connection refused`

**Solutions:**
- Verify server is reachable: `ping test.example.com`
- Check SSH key permissions: `chmod 600 ~/cwc-secrets/deployment/ssh-keys/*`
- Test SSH manually: `ssh -i ~/cwc-secrets/deployment/ssh-keys/test-server-key deploy-user@test.example.com`
- Verify SSH key path in `servers.json` is correct

### Docker Not Available

**Error:** `Docker is not installed on the server`

**Solutions:**
- SSH to server and install Docker
- Verify Docker daemon is running: `systemctl status docker`
- Add deployment user to docker group: `usermod -aG docker deploy-user`

### MariaDB Lock File Error

**Error:** `Can't lock aria control file`

**Root Cause:** Data directory conflict - multiple MariaDB instances using same data path

**Solutions:**
- Verify data path includes service name: `{deploymentName}-{serviceName}/data`
- Example: `test-cwc-database/data` vs `test-mariadb/data`
- Different deployments/services should have separate data directories

### Root Login Fails (Access Denied)

**Warning:** `Failed to connect as root: Access denied`

**Expected Behavior:**
- Root can only connect from localhost (docker exec)
- For existing data, old root password may be retained (MariaDB doesn't re-initialize)
- Use mariadb user for remote connections
- Deploy treats root connection failure as warning, not error

### MariaDB Client Command Not Found

**Error:** `mysql: command not found`

**Root Cause:** MariaDB 11.8 uses `mariadb` command, not `mysql`

**Solution:**
- Use `docker exec {container} mariadb -u...` instead of `mysql`
- Deployment handles this automatically

### Schema Not Created

**Warning:** `Database connected, but cwc schema not found`

**Root Cause:** MariaDB init scripts only run when data directory is empty

**Solutions:**
- For fresh deployment: Use `--create-schema` flag
- For existing data: Manually clear data directory or run scripts separately
- Check if data directory has leftover files: `ls {dataPath}`
- Verify init-scripts were mounted: `docker inspect {container}`

### Port Conflict

**Error:** `Failed to start container: port already in use`

**Root Cause:** Another service using the same port

**Solutions:**
- Use `--port` flag to specify different port
- Auto-calculated port range: 3306-3399 based on deployment name hash
- Check what's using the port: `netstat -tulpn | grep 3306`

### No Schemas Visible in MySQL Workbench

**Root Cause:** Database initialized with wrong credentials or incomplete initialization

**Solutions:**
- Clear data directory and redeploy with `--create-schema` flag
- Verify MARIADB_DATABASE environment variable set correctly
- Check container logs: `docker logs {container} | grep init-scripts`

### Network Conflicts

**Error:** `Failed to create network: address already in use`

**Solutions:**
- List existing networks: `docker network ls`
- Inspect network: `docker network inspect cwc-test`
- Remove unused network: `docker network rm cwc-test`
- Use different deployment name to get different network

## Deployment Philosophy

### Key Principles

1. **Deploy early, deploy often** - Deployment is not a final step; start deploying from day one to catch infrastructure issues early
2. **Separation of concerns** - Deployment flow is separate from source control (git) flow
3. **Test on server first** - Deploy to dev/test server and thoroughly test before pushing PR to GitHub
4. **No local database** - Always point to dev/test server database instance to reduce local setup complexity
5. **Isolated environments** - Support multiple simultaneous deployments for features, releases, and developer testing
6. **Timestamped builds** - Every deployment is timestamped for complete traceability and rollback capability
7. **Build artifacts outside monorepo** - Deployment builds never create files within the source repository

### Why Custom Deployment Tool?

1. **Workflow alignment:** Developer tests on server before git push (opposite of CI/CD)
2. **Separation of concerns:** Deployment separate from source control
3. **Isolated environments:** Easy multi-deployment support for testing
4. **Roll-your-own philosophy:** Minimize dependencies, full control
5. **Future option:** Can invoke custom CLI from GitHub Actions later if desired

### Why SSH-Based Deployment?

1. Works with any server (cloud-agnostic)
2. No vendor lock-in
3. Familiar tools (ssh, docker)
4. Simple mental model
5. Easy debugging (can SSH to server manually)

### Why Timestamped Builds?

1. Complete traceability (know exactly when deployed)
2. Visible in `docker ps` output
3. Enable rollback to specific version
4. Multiple versions can coexist during testing
5. Audit trail for debugging

### Why Builds Outside Monorepo?

1. Keep source tree clean
2. No accidental git commits of build artifacts
3. Easy to .gitignore entire builds directory
4. Separate concerns: source vs deployment artifacts

## Future Extensions

This deployment tool is architected for future expansion:

- **Service deployment:** Auth, API, website, dashboard microservices
- **Multi-container orchestration:** Services connecting via Docker networks
- **Environment variable injection:** Per-service configuration
- **Health checks:** Service readiness verification
- **Log aggregation:** Centralized logging across services
- **Rollback capability:** Quick revert to previous timestamp
- **Cleanup automation:** Remove old deployments older than N days

# Future Deployment Refactor Suggestions

This document captures improvement opportunities for the `cwc-deployment` package identified through code review. These are suggestions for future work - not urgent fixes, but improvements that would make the codebase easier to understand, maintain, and extend.

**Document Purpose:** Living document for tracking improvement ideas. Add your own suggestions as you work with the code.

---

## Priority 1: Code Duplication

### 1.1 Network Configuration Calculation (Duplicated in 2 files)

**Current State:**
- `src/service/deployService.ts:12-26` - `calculateNetworkConfig()`
- `src/database/deployDatabase.ts:10-24` - identical implementation

**Problem:** Same hash-based subnet calculation exists in two places. Bug fixes or changes require updating both.

**Suggested Fix:**
```typescript
// Create: src/core/network.ts
export function calculateNetworkConfig(deploymentName: string): NetworkConfig {
  // Single implementation
}
```

### 1.2 Port Calculation (Duplicated in 2 files)

**Current State:**
- `src/compose/buildCompose.ts:40-49` - `calculateDatabasePort()`
- `src/database/deployDatabase.ts:30-40` - `calculatePort()`

**Problem:** Database port range calculation (3306-3399) duplicated.

**Suggested Fix:** Move to `src/core/network.ts` or create `src/core/ports.ts`.

### 1.3 Docker Resource Cleanup Pattern (Repeated 3 times)

**Current State in `src/commands/deploy.ts:68-141`:**
```typescript
// Container cleanup (lines 68-93)
const containers = result.stdout.trim().split('\n').filter(n => n.length > 0);
if (containers.length > 0) { /* loop stop/remove */ }

// Image cleanup (lines 97-117) - IDENTICAL PATTERN
// Volume cleanup (lines 130-141) - IDENTICAL PATTERN
```

**Suggested Fix:**
```typescript
// Create helper in src/core/docker.ts
async function cleanupDockerResources(
  ssh: SSHConnection,
  resourceType: 'container' | 'image' | 'volume',
  filterPattern: string
): Promise<void>
```

### 1.4 Health Check Polling (2 Different Implementations)

**Current State:**
- `src/service/deployService.ts:58-92` - `waitForServiceReady()` polls logs
- `src/database/deployDatabase.ts:145-170` - inline MariaDB polling

**Problem:** Different timeout values (120 vs 60), different patterns, different logging.

**Suggested Fix:** Create generic `waitForCondition()` utility that accepts a check function.

---

## Priority 2: Magic Numbers & Hardcoded Values

### 2.1 Create Constants File

**Suggested:** `src/core/constants.ts`

```typescript
// Port Configuration
export const DB_PORT_BASE = 3306;
export const DB_PORT_RANGE = 94;  // 3306-3399

// Network Configuration
export const NETWORK_SUBNET_PREFIX = '192.1';
export const NETWORK_SUBNET_MASK = '/24';

// Timeouts (in seconds)
export const HEALTH_CHECK_TIMEOUT_SECONDS = 120;
export const DB_READY_TIMEOUT_SECONDS = 60;
export const SPINNER_UPDATE_INTERVAL = 10;

// Container IP Assignments
export const CONTAINER_IP_GATEWAY = 1;
export const CONTAINER_IP_DATABASE = 2;
export const CONTAINER_IP_SQL = 3;
export const CONTAINER_IP_AUTH = 4;
export const CONTAINER_IP_STORAGE = 5;
export const CONTAINER_IP_CONTENT = 6;
export const CONTAINER_IP_API = 7;

// Build Configuration
export const NODE_VERSION = 'node22';
export const MARIADB_DRIVER_VERSION = '^3.3.2';
export const BCRYPT_VERSION = '^5.1.1';
```

### 2.2 Values Currently Hardcoded

| Location | Value | Purpose |
|----------|-------|---------|
| `buildCompose.ts:47-48` | `94`, `3306` | Port range |
| `deployService.ts:43-44` | `192.1`, `.0/24` | Network config |
| `deployService.ts:81` | `120` | Health check timeout |
| `deployCompose.ts:81` | `120` | Same timeout (duplicated) |
| `deployDatabase.ts:145` | `60` | Different timeout (inconsistent) |
| `buildCompose.ts:80` | `'node22'` | Node version |
| `buildArchive.ts:84` | `'^3.3.2'`, `'^5.1.1'` | Dependency versions |

---

## Priority 3: Long Functions to Break Down

### 3.1 `deployDatabase()` - 208 lines

**Location:** `src/database/deployDatabase.ts:45-252`

**Current Responsibilities:**
1. Network calculation
2. Port calculation
3. Directory creation
4. Archive transfer
5. Archive extraction
6. Network creation
7. Docker build
8. Docker run
9. Health check polling
10. Connectivity testing
11. Summary display

**Suggested Breakdown:**
```typescript
// Keep orchestration simple
async function deployDatabase(options) {
  const config = prepareDeploymentConfig(options);
  await setupServerDirectories(ssh, config);
  await transferAndExtractArchive(ssh, archivePath, config);
  await ensureDockerNetwork(ssh, config);
  const containerId = await buildAndStartContainer(ssh, config);
  await waitForDatabaseReady(ssh, containerId, config);
  displayDeploymentSummary(config);
}
```

### 3.2 `undeployServiceCommand()` - 146 lines

**Location:** `src/commands/undeploy.ts:174-319`

**Problem:** Nearly identical to `undeployDatabaseCommand()` with service-specific logic mixed in. Same error-checking pattern repeated for container stop, container remove, image remove, network check.

**Suggested Fix:** Extract shared undeploy logic into reusable function with service-specific callbacks.

### 3.3 `cleanupExistingDeployment()` - 83 lines

**Location:** `src/commands/deploy.ts:59-142`

**Problem:** Three nearly identical blocks for containers, images, volumes.

**Suggested Fix:** See 1.3 above - extract generic cleanup function.

### 3.4 `buildNodeService()` - 98 lines

**Location:** `src/compose/buildCompose.ts:54-151`

**Problem:** SQL key copying logic (lines 110-146) is complex and could be its own function.

**Suggested Fix:**
```typescript
async function copyServiceSecrets(
  serviceType: NodeServiceType,
  serviceDir: string,
  options: ComposeDeploymentOptions
): Promise<void>
```

---

## Priority 4: Testability Improvements

### 4.1 Current State

- **Test files:** None (0% coverage)
- **Package.json:** No test script defined

### 4.2 Barriers to Testing

1. **Direct SSH calls:** Functions call `ssh.exec()` directly, no way to mock
2. **Filesystem operations:** Direct `fs` calls, no abstraction
3. **Docker commands:** Built as strings, executed via SSH
4. **Global logger:** Imported directly, can't swap for test logger
5. **Hardcoded paths:** No way to redirect to test fixtures

### 4.3 Suggested Approach

**Phase 1: Add Abstraction Layers**
```typescript
// src/core/executor.ts
interface CommandExecutor {
  exec(command: string): Promise<ExecResult>;
  copyFile(source: string, dest: string): Promise<void>;
}

class SSHExecutor implements CommandExecutor { /* wraps ssh */ }
class MockExecutor implements CommandExecutor { /* for tests */ }
```

**Phase 2: Dependency Injection**
```typescript
// Current
async function deployService(options: ServiceOptions) {
  const ssh = new SSHConnection();
  // ...
}

// Refactored
async function deployService(
  options: ServiceOptions,
  executor: CommandExecutor = new SSHExecutor(options)
) {
  // ...
}
```

**Phase 3: Add Test Suite**
- Unit tests for pure functions (port calculation, config generation)
- Integration tests with MockExecutor for deployment flows
- Snapshot tests for generated configs (docker-compose.yml, nginx.conf)

---

## Priority 5: Documentation Gaps

### 5.1 Missing JSDoc Comments

Functions that need documentation:

| Function | File | Why |
|----------|------|-----|
| `cleanupExistingDeployment` | deploy.ts | Complex, non-obvious behavior |
| `calculateNetworkConfig` | deployService.ts | Hash algorithm needs explanation |
| `waitForServiceReady` | deployService.ts | Polling logic, failure conditions |
| `buildNodeService` | buildCompose.ts | SQL key handling is complex |

### 5.2 Unclear Parameter Names

| Current | Suggested | Location |
|---------|-----------|----------|
| `keepData` | `preserveDataVolume` | undeploy.ts |
| `volumeContainerPath` | `persistentStoragePath` | config.ts |

### 5.3 Missing "Why" Comments

Add comments explaining:
- Why port range is 3306-3399 (MariaDB default + separation)
- Why subnet calculation uses hash (deterministic, no coordination)
- Why network cleanup checks for containers (avoid orphaned networks)
- Why MariaDB 11.8 uses `mariadb` command (executable renamed)

---

## Priority 6: Suggested New Files

### 6.1 `src/core/constants.ts`
Centralize all magic numbers (see Priority 2).

### 6.2 `src/core/network.ts`
```typescript
export function calculateNetworkConfig(deploymentName: string): NetworkConfig;
export function calculateDatabasePort(deploymentName: string): number;
export function getContainerIp(serviceType: ServiceType, subnetBase: string): string;
```

### 6.3 `src/core/docker.ts`
```typescript
export function buildDockerRunCommand(options: DockerRunOptions): string;
export function buildDockerBuildCommand(options: DockerBuildOptions): string;
export async function cleanupDockerResources(
  executor: CommandExecutor,
  resourceType: ResourceType,
  filter: string
): Promise<CleanupResult>;
```

### 6.4 `src/core/health.ts`
```typescript
export async function waitForCondition(
  checkFn: () => Promise<boolean>,
  options: WaitOptions
): Promise<void>;

export async function waitForServiceReady(
  executor: CommandExecutor,
  containerId: string,
  readinessPattern: string
): Promise<void>;
```

---

## Priority 7: Consistency Improvements

### 7.1 Timeout Values

| Current | Location | Suggested |
|---------|----------|-----------|
| 120 | Service health check | Use constant |
| 120 | Compose health check | Same constant |
| 60 | Database readiness | Different constant or same? |

**Decision needed:** Should database have different timeout or same as services?

### 7.2 Error Handling Patterns

Currently mixed:
1. `throw new Error(...)` - Some functions
2. `return { success: false, message }` - Result pattern
3. `process.exit(1)` - CLI commands

**Suggested:** Standardize on result pattern for all deployment operations, only use `process.exit` at CLI boundary.

### 7.3 Container/Image Naming

Pattern is used but not documented:
- Container: `{serviceName}-{deploymentName}-{timestamp}`
- Image: `{serviceName}:{deploymentName}-{timestamp}`

**Suggested:** Create named functions:
```typescript
export function getContainerName(service: string, deployment: string, timestamp: string): string;
export function getImageTag(service: string, deployment: string, timestamp: string): string;
```

---

## Architectural Considerations

### Should Legacy Single-Service Deploy Be Removed?

**Current state:** Two deployment modes exist:
1. Single-service: `deploy database`, `deploy sql`, etc.
2. Compose: `deploy-compose` (preferred)

**Options:**
1. **Keep both** - Flexibility for debugging individual services
2. **Remove single-service** - Simplify codebase, fewer code paths
3. **Deprecate but keep** - Mark as legacy, recommend compose

**Recommendation:** Keep for now, but document that compose is preferred.

### Template Strategy

**Current:** Mixed approach
- Some templates read from files (`templates/service/Dockerfile.template`)
- Some generated programmatically (`generateComposeFile()` builds YAML line by line)

**Future consideration:** Standardize on one approach. Template files are more readable; programmatic is more flexible for conditionals.

# cwc-website Package

Public-facing Next.js 15 web application with App Router and React 19 Server Components.

---

## BFF Architecture Pattern

cwc-website uses a Backend-for-Frontend (BFF) pattern where Next.js acts as a proxy layer:

```
Browser
   │
   ▼ (fetch to same origin)
/backend/* routes (Next.js Route Handlers)
   │
   ▼ (uses serviceClient.ts)
Internal services (cwc-auth:5005, cwc-api:5040, cwc-content:5008)
```

**Key benefits:**
- No CORS configuration needed (same-origin requests)
- HTTP-only cookies for JWT storage (secure, simple)
- Browser only communicates with main domain
- Internal services accessed via Docker service names

**Important distinction:**
- `serviceClient.ts` is used BY `/backend/*` route handlers to call internal services
- The browser calls `/backend/*` routes, NOT serviceClient.ts directly

**RPC-style API convention:**
- All backend routes use POST only (no GET, PUT, DELETE)
- Operations are specified in request body (e.g., `{ action: 'list' }`)
- Consistent with internal CWC services (cwc-auth, cwc-api, etc.)

---

## Critical Rules

### Server Components by Default (SEO)

**All pages must be Server Components unless they require interactivity.** This is non-negotiable for SEO.

```typescript
// ✅ Server Component (default) - data fetching, no 'use client'
export default async function SessionPage({ params }: Props) {
  const session = await fetchSession(params.sessionId);
  return <SessionViewer session={session} />;
}

// ✅ Client Component - only when interactivity needed
'use client';
export function CollapsibleSection({ children }: Props) {
  const [isOpen, setIsOpen] = useState(false);
  // ...
}
```

### Build Requirement

**Production builds require `NODE_ENV=production`:**

```bash
NODE_ENV=production pnpm website build  # ✅ Works
pnpm website build                       # ❌ Fails with Html import error
```

### Path Alias

Use `@/*` for imports from `src/`:

```typescript
import { SessionViewer } from '@/components/session/SessionViewer';
import { serviceRequest } from '@/server/serviceClient';
```

---

## Template System Architecture

### Route Groups

The app uses Next.js route groups to separate concerns:

| Route Group | Purpose | Auth Required |
|-------------|---------|---------------|
| `(site)` | Marketing pages (landing, about, privacy, terms) | No |
| `(auth)` | Authentication pages (logon, logoff, signup, password-reset) | No |
| `(content)` | Public content (project list, project detail, user profile) | No |
| `(protected)` | User actions (project-create, project-edit, user-profile-edit) | Yes |
| `(app)` | Reserved for future app-like features | TBD |

Route groups use parentheses and don't affect URLs (`/about` not `/(site)/about`).

### Next.js Enforced Filenames

These filenames are **required by Next.js** and cannot be renamed to PascalCase:

| Filename | Purpose |
|----------|---------|
| `page.tsx` | Page component |
| `layout.tsx` | Layout wrapper |
| `not-found.tsx` | 404 page |
| `error.tsx` | Error boundary |
| `loading.tsx` | Loading state |
| `route.ts` | API route handler |

The export names can be descriptive (e.g., `RootLayout`, `ProtectedRouteLayout`) for debugging clarity.

### Template Organization

Templates live in `src/templates/` with generic names for easy swapping:

- `templates/site/` - Template for the `(site)` route group
- `templates/app/` - Template for the `(app)` route group (future)

**Naming convention:** Use generic names like `SiteLayout`, `SiteHeader`, not template-specific names like `PhantomLayout`.

### Component Categories

| Category            | Location                     | Purpose                                 |
| ------------------- | ---------------------------- | --------------------------------------- |
| Template components | `templates/site/components/` | Layout structure (header, footer, menu) |
| Content components  | `components/content/`        | Page content (tiles, page headers)      |
| UI components       | `components/ui/`             | Reusable primitives (buttons, icons)    |

### Server vs Client Split for Templates

| Component       | Type   | Reason                    |
| --------------- | ------ | ------------------------- |
| SiteLayout      | Server | Static wrapper structure  |
| SiteHeader      | Server | Static logo/nav shell     |
| SiteMenu        | Client | State for open/close      |
| SiteFooter      | Server | Static content            |
| PreloadHandler  | Client | DOM manipulation on mount |
| MenuToggle      | Client | Click handler for menu    |
| TilesGrid, Tile | Server | Static content            |
| PageHeader      | Server | Static content            |

### Menu State Management

Menu state is managed via React Context (replacing jQuery):

```typescript
// templates/site/hooks/useMenu.tsx
'use client';
export function MenuProvider({ children }) {
  const [isOpen, setIsOpen] = useState(false);
  // Syncs to body class 'is-menu-visible' for CSS
  // Closes on Escape key
}

export function useMenu() {
  return useContext(MenuContext); // { isOpen, toggle, open, close }
}
```

### debugUi Prop Pattern

All content and template components support a `debugUi?: boolean` prop for development visualization:

- **Content components (red outline):** Use `debug-ui` class
- **Template components (orange outline):** Use `debug-ui-template` class
- Shows component name via `data-component` attribute tooltip

```typescript
// In page or layout file
const debugUi = true; // Toggle for development

<PageHeader title="..." debugUi={debugUi} />
<Tile title="..." debugUi={debugUi} />
```

```

**Import rules:**
- `server/` - Never import from client code
- `client/` - Always include `'use client'` directive
- `shared/` - Pure TypeScript, no React hooks or server-only APIs

### Naming Conventions

| Type        | Convention   | Example                                |
| ----------- | ------------ | -------------------------------------- |
| Page file   | `page.tsx`   | `src/app/project/[projectId]/page.tsx` |
| Layout file | `layout.tsx` | `src/app/layout.tsx`                   |
| Component   | PascalCase   | `SessionViewer.tsx`                    |
| Utility     | camelCase    | `serviceClient.ts`                     |
| Types file  | `*.types.ts` | `session.types.ts`                     |

### Component File Pattern

```typescript
// src/components/session/SessionHeader.tsx
import type { ReactNode } from 'react';
import type { CwcCodingSession } from 'cwc-types';

type SessionHeaderProps = {
  session: CwcCodingSession;
};

export function SessionHeader({ session }: SessionHeaderProps): ReactNode {
  return (
    <header>
      <h1>{session.summary}</h1>
    </header>
  );
}
```

---

## Page Patterns

### Dynamic Route with Metadata

```typescript
// src/app/project/[projectId]/session/[sessionId]/page.tsx
import type { Metadata } from 'next';
import { notFound } from 'next/navigation';

type PageProps = {
  params: Promise<{ projectId: string; sessionId: string }>;
};

// Dynamic metadata for SEO
export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    return { title: 'Not Found' };
  }

  return {
    title: session.summary,
    description: session.description,
    openGraph: {
      title: session.summary,
      type: 'article',
    },
  };
}

// Page component (Server Component by default)
export default async function SessionPage({ params }: PageProps) {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    notFound();
  }

  return <SessionViewer session={session} />;
}
```

### Static Metadata

```typescript
// src/app/page.tsx
import type { Metadata } from 'next';

export const metadata: Metadata = {
  title: 'Coding with Claude',
  description: 'Browse developer projects and AI coding sessions',
};

export default function HomePage() {
  return <main>...</main>;
}
```

---

## Data Fetching Patterns

### API Client Pattern

```typescript
// src/lib/cwc-api-client.ts
import type { CwcProject } from 'cwc-types';

const API_URL = process.env.CWC_API_URL;

export const cwcApiClient = {
  async getProject(projectId: string): Promise<CwcProject | undefined> {
    const response = await fetch(`${API_URL}/api/v1/project/${projectId}`, {
      next: { revalidate: 60 }, // Cache 1 minute
    });

    if (!response.ok) {
      if (response.status === 404) return undefined;
      throw new Error(`Failed to fetch: ${response.statusText}`);
    }

    return response.json();
  },
};
```

### Caching Rules

| Data Type       | Revalidation   | Rationale              |
| --------------- | -------------- | ---------------------- |
| Session content | 3600s (1 hour) | Immutable after upload |
| User profiles   | 300s (5 min)   | Occasionally updated   |
| Project list    | 60s (1 min)    | Frequently updated     |

---

## Client Component Rules

**Only use 'use client' when component needs:**

- useState, useEffect, useRef
- Event handlers (onClick, onChange)
- Browser APIs (localStorage, window)

```typescript
// ✅ Needs 'use client' - has state
'use client';

import { useState } from 'react';

export function Collapsible({ children }: Props) {
  const [open, setOpen] = useState(false);
  return (
    <div>
      <button onClick={() => setOpen(!open)}>Toggle</button>
      {open && children}
    </div>
  );
}

// ❌ Does NOT need 'use client' - pure render
export function Badge({ label }: Props) {
  return <span className="badge">{label}</span>;
}
```

---

## Error Handling

### Route Error Boundary

```typescript
// src/app/project/[projectId]/error.tsx
'use client'; // Error boundaries must be Client Components

type ErrorProps = {
  error: Error;
  reset: () => void;
};

export default function Error({ error, reset }: ErrorProps) {
  return (
    <div>
      <h2>Something went wrong</h2>
      <button onClick={reset}>Try again</button>
    </div>
  );
}
```

### Not Found

```typescript
// In page component
import { notFound } from 'next/navigation';

if (!data) {
  notFound(); // Renders src/app/not-found.tsx
}
```

---

## What to Check During Planning

1. **Server vs Client Component:** Does this component need interactivity? If no, keep as Server Component
2. **Metadata:** Does this page need dynamic SEO metadata? Use `generateMetadata`
3. **Data fetching:** Is caching strategy appropriate for data freshness needs?
4. **Error states:** Is there an error boundary for this route?
5. **Loading states:** Should there be a loading.tsx for slow data fetches?
6. **Types:** Are props typed correctly with cwc-types?

---

## Common Mistakes to Avoid

| Mistake                       | Correct Approach                                           |
| ----------------------------- | ---------------------------------------------------------- |
| Adding 'use client' to pages  | Keep pages as Server Components, extract interactive parts |
| Fetching in Client Components | Fetch in Server Components, pass data as props             |
| Missing metadata              | Every public page needs title/description                  |
| Using `useEffect` for data    | Use async Server Components instead                        |
| Hardcoding URLs               | Use environment variables                                  |

---

## Environment Variables

**Setup:** Run `pnpm config-helper generate` to create `.env` files, or copy `.env.local.example` to `.env.local`.

| Variable | Purpose | Used By |
|----------|---------|---------|
| `AUTH_URI` | cwc-auth service URL | serviceClient.ts |
| `API_URI` | cwc-api service URL | serviceClient.ts |
| `CONTENT_URI` | cwc-content service URL | serviceClient.ts |
| `APP_URL` | Public website URL | Server Components |

**Production values** (Docker service names):
```
AUTH_URI=http://cwc-auth:5005/auth/v1
API_URI=http://cwc-api:5040/api/v1
CONTENT_URI=http://cwc-content:5008/content/v1
```

**Local development values**:
```
AUTH_URI=http://localhost:5005/auth/v1
API_URI=http://localhost:5040/api/v1
CONTENT_URI=http://localhost:5008/content/v1
```

**Rule:** All service URLs are server-only (used by Route Handlers). Browser never calls services directly.

---

## Deployment (Future - Not Yet Implemented)

### Key Difference from Backend Services

**Next.js requires environment variables at BUILD time, not runtime.**

| Service Type            | When Env Vars Needed      | How Currently Handled                 |
| ----------------------- | ------------------------- | ------------------------------------- |
| Backend (cwc-api, etc.) | Runtime (`docker run -e`) | Passed via docker run flags           |
| Next.js (cwc-website)   | Build time (`next build`) | Must be in `.env` during docker build |

### Docker Deployment Pattern for Next.js

```dockerfile
# Environment file must be present BEFORE next build
COPY .env.production .env.production
RUN npm run build

# Built app has env vars baked in
CMD ["npm", "start"]
```

### Deployment Workflow (When Implemented)

1. cwc-deployment copies `{env}.cwc-website.env` from cwc-secrets to build context
2. Dockerfile copies env file and runs `next build`
3. Environment variables are baked into the JavaScript bundle
4. Container runs `next start` (no runtime env injection needed)

### Env Files in cwc-secrets

Follow the existing naming convention:

- `dev.cwc-website.env`
- `test.cwc-website.env`
- `prod.cwc-website.env`

Location: `~/cwc/private/cwc-secrets/env/`

### Prerequisites Before Deployment

1. **cwc-content service** - Must be implemented first (handles auth + content access)
2. **cwc-deployment updates** - Add website service type to deployment CLI

---

## SCSS and Styling

### SCSS Organization

Styles use SCSS with Next.js built-in compilation:

- `globals.scss` imports the template's `main.scss`
- Each template has its own SCSS in `templates/{template}/styles/`
- Use CSS custom properties for theming

### CSS Custom Properties

```scss
// templates/site/styles/_variables.scss
:root {
  --color-accent1: #f2849e;
  --color-accent2: #7ecaf6;
  --color-accent3: #7bd0c1;
  --color-accent4: #c75b9b;
  --color-accent5: #ae85ca;
  --color-accent6: #8499e7;
  --color-bg: #1a1a2e;
  --font-family: var(--font-source-sans), Helvetica, sans-serif;
}
```

### Tile Gradients (No Images)

Tiles use CSS gradients instead of images:

```scss
// Each style gets a unique gradient
.tiles article.style1 > .image {
  background: linear-gradient(
    135deg,
    var(--color-accent1),
    color-mix(in srgb, var(--color-accent1), #000 40%)
  );
}
```

### Icons with react-icons

Use `react-icons` for all icons:

```typescript
import { FaGithub, FaTwitter } from 'react-icons/fa';
import { IoMenu, IoClose } from 'react-icons/io5';
```

## Getting Started

### Prerequisites

- Node.js 22+ (see `.nvmrc` in monorepo root)
- pnpm 9+

### Installation

From the monorepo root:

```bash
# Install all dependencies
pnpm install
```

### Development

```bash
# Start development server
pnpm website dev
```

The development server runs at [http://localhost:3000](http://localhost:3000).

#### Debug UI Mode

Components support a `debugUi` prop for visualizing layout boundaries:

```tsx
// In page.tsx or layout.tsx
const debugUi = true; // Toggle for development

<PageHeader title="..." debugUi={debugUi} />
<Tile title="..." debugUi={debugUi} />
```

- **Red outlines** - Content components (`components/content/`)
- **Orange outlines** - Template components (`templates/site/components/`)
- **Tooltips** - Show component names on hover

### Build

```bash
# Production build
NODE_ENV=production pnpm website build

# Start production server
pnpm website start
```

> **Note:** The `NODE_ENV=production` is required for the build to succeed due to Next.js internal page generation.

### Type Checking

```bash
pnpm website typecheck
```

## Architecture

### BFF (Backend-for-Frontend) Pattern

cwc-website uses Next.js as a proxy layer between the browser and backend services:

```
┌─────────────────────────────────────────────────────────────┐
│                         Browser                              │
│                            │                                 │
│                            ▼                                 │
│              codingwithclaude.dev/backend/*                  │
└─────────────────────────────────────────────────────────────┘
                             │
                             ▼
┌─────────────────────────────────────────────────────────────┐
│                    cwc-website:3000                          │
│                     (Next.js BFF)                            │
│                            │                                 │
│              ┌─────────────┼─────────────┐                   │
│              ▼             ▼             ▼                   │
│        cwc-auth:5005  cwc-api:5040  cwc-content:5008         │
│         (internal)     (internal)     (internal)             │
└─────────────────────────────────────────────────────────────┘
```

**Key benefits:**
- Browser only communicates with the main domain (same-origin)
- No CORS configuration needed
- HTTP-only cookies for secure JWT storage
- Internal services accessed via Docker service names

### Route Groups

| Route Group | Purpose |
|-------------|---------|
| `(site)` | Marketing pages (landing, about, privacy, terms) |
| `(auth)` | Authentication pages (logon, logoff, signup, password-reset) |
| `(content)` | Public content (project list, project detail, user profile) |
| `(protected)` | Authenticated pages (project-create, project-edit, user-profile-edit) |
| `(app)` | Reserved for future app-like features |

Route groups use parentheses and don't affect URLs (`/about` not `/(site)/about`).

### Template System

Templates are organized in `src/templates/` for easy swapping:
- Each template provides layout components, styles, and hooks
- Templates use generic names (`SiteLayout` not `PhantomLayout`) for portability
- Content components in `src/components/` are template-agnostic

**Current template:** Based on [HTML5 UP Phantom](https://html5up.net/phantom), converted from jQuery to React.

### Server Components (Default)

All pages use React Server Components by default for:
- **SEO** - Full HTML rendered on server for search crawlers
- **Performance** - No JavaScript bundle for static content
- **Data Fetching** - Async data loading without client-side effects

### Client Components

Used only when interactivity is required:
- Menu toggle and off-canvas navigation
- Authentication state (AuthProvider)
- Data mutations (React Query)
- Copy-to-clipboard buttons

Mark with `'use client'` directive at the top of the file.

### Styling

- **SCSS** - Next.js built-in SCSS compilation
- **CSS Custom Properties** - Theming via `:root` variables
- **Gradient backgrounds** - Tiles use CSS gradients instead of images
- **react-icons** - Icon components from Font Awesome, Ionicons, etc.

## Environment Variables

Generate environment files using the configuration helper:

```bash
pnpm config-helper generate
```

Or copy the example file for local development:

```bash
cp .env.local.example .env.local
```

### Available Variables

| Variable | Description | Example (Production) |
|----------|-------------|----------------------|
| `AUTH_URI` | cwc-auth service URL | `http://cwc-auth:5005/auth/v1` |
| `API_URI` | cwc-api service URL | `http://cwc-api:5040/api/v1` |
| `CONTENT_URI` | cwc-content service URL | `http://cwc-content:5008/content/v1` |
| `APP_URL` | Public website URL | `https://codingwithclaude.dev` |

**Note:** All service URLs are server-side only (used by Route Handlers). The browser communicates only with `/backend/*` routes on the same origin.

## SEO

### Metadata

Each page exports metadata for search engines:

```typescript
export const metadata: Metadata = {
  title: 'Page Title',
  description: 'Page description for search results',
  openGraph: { /* social sharing */ },
};
```

Dynamic pages use `generateMetadata()` for data-dependent metadata.

### Sitemap

The sitemap is generated at `/sitemap.xml` using Next.js conventions:

```typescript
// src/app/sitemap.ts
export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
  // Fetch published sessions and generate URLs
}
```

## Scripts

| Command | Description |
|---------|-------------|
| `pnpm website dev` | Start development server |
| `pnpm website build` | Create production build |
| `pnpm website start` | Start production server |
| `pnpm website typecheck` | Run TypeScript type checking |

## Dependencies

### Workspace Packages

- `cwc-types` - Shared TypeScript type definitions

### External Dependencies

- `next` - React framework
- `react` / `react-dom` - UI library
- `@tanstack/react-query` - Data fetching and caching
- `sass` - SCSS compilation
- `react-icons` - Icon components

# Docker Compose Migration Plan

This document captures the architectural analysis and migration strategy for transitioning cwc-deployment from manual Docker orchestration to Docker Compose.

## Current Architecture

### SSH-Based Manual Docker Orchestration

The cwc-deployment package is a custom Node.js CLI that:
- Connects to remote servers via SSH with key-based authentication
- Builds Docker images locally and transfers them to remote servers
- Manages container lifecycle (create, run, stop, remove) via SSH
- Uses idempotent design (deploy = cleanup + build + run)

### Current Networking Approach

**Static IP Allocation:**
```
Network Name:    cwc-{deploymentName}
Network Type:    Docker bridge network
Subnet Pattern:  192.1.{N}.0/24  (where N = hash(deploymentName) % 254 + 1)
Container IP:    192.1.{N}.2     (fixed within deployment)
External Port:   3306-3399       (hash-based auto-allocation for databases)
```

**How It Works:**
1. Hash deployment name to generate unique subnet number (1-254)
2. Create Docker bridge network: `docker network create --driver bridge --subnet 192.1.{N}.0/24 cwc-{deploymentName}`
3. Attach containers with static IPs

**Current Status:**
- Only database deployments implemented
- No service-to-service communication yet
- Perfect time to migrate before adding more services

---

## Docker Compose Benefits

### DNS-Based Service Discovery

Docker Compose automatically provides DNS resolution for services:

```yaml
services:
  cwc-sql:
    build: ./packages/cwc-sql
    # Other services reach it via "cwc-sql:5020"

  cwc-auth:
    environment:
      - DATA_URI=http://cwc-sql:5020/data/v1  # DNS name, not IP!
    depends_on:
      - cwc-sql
```

### Comparison

| Aspect | Manual IPs | Docker Compose DNS |
|--------|-----------|-------------------|
| Service discovery | Hardcoded IPs | Automatic via service names |
| Scaling | Must assign new IPs | `docker compose up --scale cwc-sql=3` |
| Load balancing | Manual nginx config | Docker handles round-robin |
| Config changes | Update IPs everywhere | Change once in compose file |
| Local dev | Different IPs than prod | Same service names work everywhere |

---

## Migration Strategy

### Phase 1: Database Service (Current)

1. Create `docker-compose.yml` template for database
2. Map current environment variables to compose format
3. Replace `docker run` commands with `docker-compose up`
4. Test with existing deployment workflow

**Example docker-compose.yml:**
```yaml
version: '3.8'
services:
  cwc-database:
    image: mariadb:11.4
    container_name: cwc-database-${DEPLOYMENT_NAME}
    environment:
      MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD}
      MARIADB_DATABASE: cwc
      MARIADB_USER: ${DB_USER}
      MARIADB_PASSWORD: ${DB_PASSWORD}
    volumes:
      - ${DATA_PATH}:/var/lib/mysql
      - ./mariadb.cnf:/etc/mysql/conf.d/mariadb.cnf
    ports:
      - "${EXTERNAL_PORT}:3306"
    networks:
      - cwc-network

networks:
  cwc-network:
    driver: bridge
```

### Phase 2: Multi-Service Deployments

1. Remove static IP calculations from deployment code
2. Use service names for inter-service communication
3. Update application configs to use DNS names
4. Add service health checks to compose file

**Example multi-service compose:**
```yaml
version: '3.8'
services:
  cwc-database:
    image: mariadb:11.4
    # ... database config

  cwc-sql:
    build: ./packages/cwc-sql
    environment:
      - DATABASE_SERVER=cwc-database
      - DATABASE_PORT=3306
    depends_on:
      - cwc-database

  cwc-auth:
    build: ./packages/cwc-auth
    environment:
      - DATA_URI=http://cwc-sql:5020/data/v1
    depends_on:
      - cwc-sql

  cwc-api:
    build: ./packages/cwc-api
    environment:
      - DATA_URI=http://cwc-sql:5020/data/v1
      - AUTH_URI=http://cwc-auth:5005/auth/v1
    depends_on:
      - cwc-sql
      - cwc-auth

  nginx:
    image: nginx:alpine
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - cwc-api
      - cwc-auth

networks:
  default:
    driver: bridge
```

### Phase 3: Feature Parity

Maintain existing capabilities:
- Idempotent deployments with `docker-compose down` + `docker-compose up`
- Keep cleanup logic for old containers/images
- Preserve data directory persistence strategy
- Keep timestamp-based deployment tracking

---

## Security: Network Isolation vs IP Allowlisting

### Previous Approach: IP Allowlisting

Services had `serviceApiAllowedIps` configuration to whitelist which IPs could connect.

### New Approach: Docker Network Isolation

**Why network isolation is better:**
1. Services on different Docker networks cannot communicate at all
2. No need to manage IP addresses
3. Simpler configuration
4. Works identically in dev and prod

**Implementation:**
- Each deployment gets its own Docker network
- Only services in the same network can communicate
- External access only through nginx (exposed ports)

```yaml
# Production deployment
networks:
  cwc-prod:
    driver: bridge
    internal: false  # nginx can expose to outside

# Services can only talk to each other within cwc-prod network
```

---

## SSH Deployment Flow Changes

### Current Flow
1. Build Docker image locally
2. Create tar.gz archive with Dockerfile + scripts
3. Transfer archive to server via SSH
4. Extract and run `docker build` + `docker run` via SSH

### New Flow with Compose
1. Generate `docker-compose.yml` from template
2. Generate `.env` file with deployment-specific values
3. Transfer both files to server via SSH
4. Run `docker-compose up -d` via SSH
5. For cleanup: `docker-compose down`

**Key changes to deployment code:**
- Replace `buildArchive()` with compose file generation
- Replace `docker run` commands with `docker-compose` commands
- Keep SSH-based execution (no Docker daemon API needed)

---

## Configuration Impact

### cwc-configuration-helper Changes

The centralized configuration in `configuration.ts` now uses:

**For prod/test (Docker Compose):**
```typescript
dataUri: 'http://cwc-sql:5020/data/v1',    // DNS name
authUri: 'http://cwc-auth:5005/auth/v1',   // DNS name
```

**For dev/unit/e2e (localhost):**
```typescript
dataUri: 'http://localhost:5020/data/v1',  // localhost
authUri: 'http://localhost:5005/auth/v1',  // localhost
```

### Removed Configuration

- `ipAddress` field - not needed with DNS
- `serviceApisAllowed` field - rely on network isolation

### Kept Configuration

- `port` field - still needed for both Docker and localhost scenarios
- Unique ports per service allow hybrid dev approach (run with or without Docker)

---

## Timeline Considerations

This migration can be done incrementally:

1. **Immediate:** Update cwc-configuration-helper to use DNS names for prod/test
2. **Next service deployment:** Implement Phase 1 (database with compose)
3. **When deploying auth/api:** Implement Phase 2 (multi-service)
4. **Ongoing:** Implement Phase 3 features as needed

No rush - current deployment works fine. This document preserves the analysis for when we're ready.

- [x] Update `README.md` with setup instructions

---

## Phase 2: Authentication & Context Layer

**Architecture Decision:** cwc-api does NOT duplicate JWT verification logic. Instead, cwc-api
calls cwc-auth's `/auth/v1/verify-token` endpoint to validate tokens. This keeps auth logic
centralized in cwc-auth (single source of truth) at the cost of an additional HTTP call per request.

**Architecture Refinement (Session 020):** Shared types moved to cwc-types, AuthClient moved to
cwc-backend-utils for reuse by other services.

### Prerequisites (cwc-auth work)
- [x] Add `/auth/v1/verify-token` endpoint to cwc-auth ServiceApiV1
  - Input: JWT token (from Authorization header)
  - Output: `{ success: true, payload: UserJwtPayload }` or `{ success: false, error: ... }`

### Shared Auth Types (cwc-types)
- [x] Create `cwc-types/src/authTypes.ts`
  - [x] Define `UserJwtPayload` type (moved from cwc-auth for sharing)
  - [x] Define `CwcRole` type: `'project-owner' | 'logged-on-user' | 'guest-user'`
  - [x] Define `VerifyTokenResponse` types (success/error)
  - [x] Define `VerifyTokenResult` type
- [x] Update cwc-auth to import `UserJwtPayload` from cwc-types

### AuthClient (cwc-backend-utils)
- [x] Create `cwc-backend-utils/src/AuthClient/AuthClient.ts`
  - [x] HTTP POST to cwc-auth `/auth/v1/verify-token`
  - [x] Handles success and error responses
  - [x] Returns typed `VerifyTokenResult`
- [x] Export from `cwc-backend-utils/src/index.ts`

### Request Context (cwc-api)
- [x] Create `src/context/context.types.ts`
  - [x] Define `AuthenticatedContext` and `GuestContext` types
  - [x] Define `RequestContext` union type
- [x] Create `src/context/createContext.ts`
  - [x] Uses AuthClient.verifyToken()
  - [x] Returns authenticated context on success
  - [x] Returns guest context on failure (no JWT, invalid, expired)
- [x] Create `src/context/index.ts`

### Unit Tests
- [x] Create `src/__tests__/mocks/authClient.mock.ts` - AuthClient mock helpers
- [x] Create `src/__tests__/context/createContext.test.ts` - Test authenticated and guest contexts (10 tests)

### Security Review
- [x] Verify cwc-auth endpoint validates JWT signature (HS256, proper secret)
- [x] Verify expired tokens are rejected by cwc-auth
- [x] Verify invalid tokens create guest context (no error details leaked to client)
- [x] Verify guest context has no elevated privileges
- [x] Verify userPkId comes from cwc-auth response, not request body

### Documentation Updates
- [ ] Update `CLAUDE.md` with auth integration patterns
- [ ] Update `README.md` with authentication details

---

## Phase 3: Handler Architecture

**Architecture Refinement (Session 021):** Session renewal happens on EVERY request (queries and mutations)
to keep sessions active, not just on specific triggers. This is the RPC-style approach where all
endpoints use POST.

### Prerequisites (cwc-types, cwc-backend-utils)
- [x] Add `RenewSessionResult` types to cwc-types/authTypes.ts
- [x] Add `renewSession()` method to AuthClient in cwc-backend-utils
- [x] Update AuthClient mocks in cwc-api with renewSession helpers

### Route Handler
- [x] Create `src/handlers/handler.types.ts`
  - [x] Define error codes (`CwcApiErrorCode`)
  - [x] Define response types (`CwcApiSuccessResponse`, `CwcApiErrorResponse`, `CwcApiHandlerResponse`)
  - [x] Define route config types (`CwcApiRouteConfig`, `CwcApiHandlerType`)
  - [x] Define operation types (`OperationContext`, `OperationResult`, `CwcApiOperation`)
  - [x] Define handler options types (`RouteHandlerOptions`, `QueryHandlerOptions`, `MutationHandlerOptions`)
  - [x] Define access policy stubs for Phase 4 (`RouteAccessResult`, `OperationAccessResult`)
- [x] Create `src/handlers/RouteHandler.ts`
  - [x] Check route-level access policy (role vs allowedRoles)
  - [x] Build operation context from path params
  - [x] Delegate to QueryHandler or MutationHandler based on handlerType
  - [x] Return 401 for unauthenticated access denied
  - [x] Return 403 for authenticated but unauthorized
- [x] Create `src/handlers/QueryHandler.ts`
  - [x] Operation-level access check (stub for Phase 4)
  - [x] Execute query operation
  - [x] Renew session (always, to keep session active)
  - [x] Format response with data, pagination, and new JWT
- [x] Create `src/handlers/MutationHandler.ts`
  - [x] Operation-level access check (stub for Phase 4)
  - [x] Execute mutation operation
  - [x] Renew session (always, to keep session active)
  - [x] Format response with data and new JWT
- [x] Create `src/handlers/index.ts`

### Unit Tests
- [x] Create `src/__tests__/handlers/RouteHandler.test.ts` (14 tests)
- [x] Create `src/__tests__/handlers/QueryHandler.test.ts` (15 tests)
- [x] Create `src/__tests__/handlers/MutationHandler.test.ts` (15 tests)
- [x] Create `src/__tests__/mocks/routeConfig.mock.ts`
  - [x] `createMockRouteConfig()`, `createMockOperationContext()`
  - [x] `createMockGuestContext()`, `createMockAuthenticatedContext()`
  - [x] `mockOperationSuccess()`, `mockOperationFailure()`, `mockOperationThrows()`

### Security Review
- [x] Verify error responses don't leak internal details (errorDetail only in dev mode)
- [x] Verify operation access check is stubbed (always allowed for Phase 3)
- [x] Verify session renewal failure doesn't fail the request (graceful degradation)
- [x] Verify guest users don't get session renewal

### Documentation Updates
- [x] Update `CLAUDE.md` with handler architecture patterns
- [ ] Update `README.md` with request pipeline details

---

## Phase 4: Access Policy System

### Policy Types
- [x] Create `src/policies/policy.types.ts`
  - [x] Re-export `RouteAccessResult`, `OperationAccessResult` from handler.types.ts

### Route Policies
- [x] Create `src/policies/checkRouteAccess.ts`
  - [x] Check authentication only (no ownership check)
  - [x] Uses role hierarchy: guest-user < logged-on-user < project-owner

### Operation Policies
- [x] Create `src/policies/checkOperationAccess.ts`
  - [x] Check authentication AND ownership for project-owner routes
  - [x] `isProjectOwner()` helper uses `context.ownedProjects.includes(projectId)`
  - [x] `effectiveRole` determines the user's role for this operation

### Policy Enforcement
- [x] Update `src/handlers/handler.types.ts` - Replace `allowedRoles[]` with `requiredRole: CwcRole`
- [x] Update `src/handlers/RequestHandler.ts` - Use imported `checkRouteAccess`
- [x] Update `src/handlers/QueryHandler.ts` - Use imported `checkOperationAccess`
- [x] Update `src/handlers/MutationHandler.ts` - Use imported `checkOperationAccess`
- [x] Create `src/policies/index.ts`

### Unit Tests
- [x] Create `src/__tests__/policies/checkRouteAccess.test.ts`
- [x] Create `src/__tests__/policies/checkOperationAccess.test.ts`
- [x] Update `src/__tests__/mocks/routeConfig.mock.ts` - Use `requiredRole`
- [x] Update existing handler tests to use `requiredRole`

### Security Review
- [x] Verify no privilege escalation paths (guest → user, user → owner)
- [x] Verify ownership checks use `context.ownedProjects` from JWT (not request body)
- [x] Verify `projectId` comes from path params (`operationContext`), not payload
- [x] Verify route-level only checks authentication (no DB lookup for ownership)
- [x] Verify generic error messages in production (`errorDetail` only in dev)

### Documentation Updates
- [x] Update `CLAUDE.md` with access policy patterns
- [ ] Update `README.md` with role-based access details

## Session Notes

<!-- Add notes about decisions, blockers, or context for future sessions -->

### Session 1
- Initial checklist created
- Specification reviewed and clarified:
  - Guest access: Create context with 'guest-user' role for unauthenticated requests
  - Session renewal: cwc-api calls cwc-auth /renew-session
  - Pagination: Offset-based (page/pageSize)
  - Soft delete: All content tables
  - RouteHandler class chosen over middleware approach
  - SqlFunction naming: `list` instead of `selectMultiple`
  - Added read-only SqlFunctions for featureFlag and user (limited fields)

### Session 2 (020)
- **Phase 1 COMPLETED**
  - Added `dev` script to package.json using `tsx` (better ESM support than ts-node)
  - Fixed cwc-backend-utils ESM issues:
    - `loadDotEnv.ts`: Added ESM-compatible `__dirname` using `import.meta.url`
    - `express/service.ts`: Fixed wildcard route syntax for path-to-regexp 8.x (`/*` → `/{*splat}`)
  - Service starts successfully and health check responds (POST /health/v1)

- **Architecture Decision: Centralized Authentication**
  - cwc-api will NOT duplicate JWT verification logic
  - cwc-api will call cwc-auth's `/auth/v1/verify-token` endpoint
  - Trade-off: Additional HTTP call per request, but auth logic stays centralized
  - **BLOCKER:** Phase 2 cannot proceed until cwc-auth has `/verify-token` endpoint

- **Phase 2 Revised**
  - Updated checklist to reflect API-call approach
  - Removed local JWT utilities (verifyUserJwt, extractJwtFromHeader)
  - Added prerequisite: cwc-auth must implement /verify-token first

- **Phase 2 COMPLETED**
  - Implemented shared auth types in cwc-types (`src/authTypes.ts`):
    - `UserJwtPayload`, `CwcRole`, `VerifyTokenResponse`, `VerifyTokenResult`
  - Updated cwc-auth to import `UserJwtPayload` from cwc-types (backwards-compatible re-export)
  - Created `AuthClient` in cwc-backend-utils (`src/AuthClient/`):
    - HTTP client for cwc-auth, similar pattern to SqlClient
    - `verifyToken(authHeader)` returns typed `VerifyTokenResult`
    - Handles 401 responses, network errors, timeouts
  - Created context layer in cwc-api (`src/context/`):
    - `context.types.ts`: `AuthenticatedContext`, `GuestContext`, `RequestContext`
    - `createContext.ts`: Uses AuthClient, returns authenticated or guest context
  - Created test mocks (`src/__tests__/mocks/authClient.mock.ts`):
    - `createMockAuthClient()`, `createMockUserJwtPayload()`
    - `mockVerifyTokenSuccess()`, `mockVerifyTokenFailure()`
  - All 10 context tests pass, all 38 cwc-api tests pass
  - All affected packages typecheck: cwc-types, cwc-auth, cwc-backend-utils, cwc-api
  - **Note:** AuthClient unit tests deferred (cwc-backend-utils has no test infrastructure)
    - Functionality verified through cwc-api context tests

### Session 3 (021)
- **Phase 3 COMPLETED**
  - Added `RenewSessionResult` types to cwc-types/authTypes.ts
  - Added `renewSession()` method to AuthClient in cwc-backend-utils
  - Created handler architecture:
    - `handler.types.ts`: Error codes, response types, route config, operation types, access policy stubs
    - `RouteHandler.ts`: Route access check, delegates to Query/MutationHandler
    - `QueryHandler.ts`: Execute query, renew session, format response
    - `MutationHandler.ts`: Execute mutation, renew session, format response
  - Created comprehensive test mocks (`routeConfig.mock.ts`):
    - `createMockRouteConfig()`, `createMockOperationContext()`
    - `createMockGuestContext()`, `createMockAuthenticatedContext()`
    - `mockOperationSuccess()`, `mockOperationFailure()`, `mockOperationThrows()`
  - Updated config mocks with consistent naming: `getUnitConfig()`, `createDevConfig()`, `createProdConfig()`
  - All 44 handler tests pass (14 RouteHandler + 15 QueryHandler + 15 MutationHandler)

- **Key Design Decisions:**
  - Session renewal on EVERY request (not just triggers) to keep sessions active
  - RPC-style API: All endpoints use POST, no GET/PUT/DELETE
  - Graceful degradation: Session renewal failure doesn't fail the request
  - Operation access check stubbed for Phase 4 (always allowed for now)

### Session 4 (023)
- **Phase 4 COMPLETED**
  - Created policy module (`src/policies/`):
    - `policy.types.ts`: Re-exports RouteAccessResult, OperationAccessResult
    - `checkRouteAccess.ts`: Route-level authentication check
    - `checkOperationAccess.ts`: Operation-level access with ownership check
    - `isProjectOwner()` helper function
    - `index.ts`: Exports
  - Updated handler types:
    - Replaced `allowedRoles: CwcRole[]` with `requiredRole: CwcRole`
    - Single field for both route and operation level access control
  - Updated handlers to use policy functions:
    - RequestHandler uses `checkRouteAccess(context, routeConfig.requiredRole)`
    - QueryHandler uses `checkOperationAccess(context, operationContext, routeConfig.requiredRole)`
    - MutationHandler uses same pattern as QueryHandler
  - Created policy tests:
    - `checkRouteAccess.test.ts` (9 tests)
    - `checkOperationAccess.test.ts` (14 tests)
  - Updated all handler tests to use `requiredRole`
  - All 121 tests pass

- **Key Design Decisions:**
  - **Role Hierarchy:** `guest-user < logged-on-user < project-owner`
  - **Two-Level Access Control:**
    - Route-level: Only checks authentication (no DB lookup)
    - Operation-level: Checks authentication AND ownership for `project-owner`
  - **requiredRole interpretation differs by level:**
    - Route: `project-owner` means "must be authenticated"
    - Operation: `project-owner` means "must own the project"
  - **Ownership from JWT only:** Uses `context.ownedProjects.includes(projectId)`, no database lookup
  - **projectId from path params:** Comes from `operationContext.projectId`, not request body (security)

### Session 5 (024)
- **Phase 5 COMPLETED**
  - Created SqlFunction layer with 8 content tables + 2 read-only tables:
    - Content: project, codingSession, codingSessionContent, codingSessionAttachment, comment, reaction, contentReport, abuseReport
    - Read-only: featureFlag, user (limited fields via SafeUser type)
  - Created comprehensive test infrastructure:
    - `src/__tests__/mocks/sqlClient.mock.ts` with helper functions
    - `src/__tests__/sql/project.test.ts` as reference test suite (143 tests total)
  - All tests passing (143 cwc-api, 116 cwc-sql)

- **Key Design Decisions:**
  - **Insert/Update return complete entity data:** Functions return `SqlInsertResult<T>` and `SqlUpdateResult<T>` with full entity after follow-up SELECT. This provides consistent behavior - callers always receive the complete record.
  - **Boolean abstraction:** Use `true`/`false` not `1`/`0` for boolean fields (`enabled: true`). MariaDB driver handles conversion automatically.
  - **Idempotent softDelete:** `softDelete*` functions succeed whether record is enabled or already disabled. Only returns `notFound` if record doesn't exist. No `enabled` filter in softDelete - this makes them safe to retry.
  - **`enabled` field semantics:**
    - `enabled: false` = soft-deleted (invisible to users in normal queries)
    - NOT for user-controlled disable (use `published` field for that)
    - `update*` functions filter on `enabled: true` (can't update deleted records)
    - Admin API will handle disabled records differently
  - **Access policies in handlers, not SqlFunctions:** SqlFunctions are policy-free; access checks happen in Query/MutationHandler. This keeps SqlFunctions simple, testable, and reusable.
  - **Mock helpers updated:**
    - `mockInsertSuccess<T>(client, insertId, entityData)` - provide complete entity for follow-up SELECT
    - `mockUpdateSuccess<T>(client, entityData)` - provide complete entity for follow-up SELECT
    - `mockUpdateNoOp<T>(client, entityData)` - for empty values object case

### Session 6 (025)
- **Phase 6 Entity Implementation STARTED**
  - Established consistent operation function pattern across all entities
  - Updated all 37 operation files + routes.ts to new pattern
  - All 168 tests passing

- **Operation Function Pattern Established:**
  - Options type: `{ sqlClient, payload, requestContext }`
  - Object-style `checkOperationAccess({ sqlClient, requestContext, payload, requiredRole })`
  - `RequestContext` union type (replaces old `OperationContext` wrapper)
  - Proper `userPkId` extraction with TypeScript narrowing comment
  - Descriptive comments (no numbered prefixes)
  - Route pattern: `operation: (payload, requestContext) => fn({ sqlClient, payload, requestContext })`

- **Entities Completed:**
  - 6.1 Project (5 operations)
  - 6.2 Coding Session (5 operations)
  - 6.3 Coding Session Content (5 operations)
  - 6.4 Coding Session Attachment (5 operations)
  - 6.5 Comment (5 operations)
  - 6.6 Reaction (4 operations - no update, reactions are immutable)
  - 6.7 Content Report (4 operations - no delete, reports cannot be deleted)
  - 6.8 Abuse Report (4 operations - no delete, reports cannot be deleted)

- **Test Fix Required:**
  - `RequestHandler.test.ts` expected `{ context }` wrapper but operations now receive `requestConte

# Conversation and File Rendering: Split Pane Layout

This document captures the architecture and implementation details of the split-pane layout for rendering Claude Code session transcripts with side-by-side conversation and file views.

---

## Overview

The split-pane layout provides a VS Code-inspired interface for viewing Claude Code sessions:
- **Left pane (40%)**: Conversation between user and Claude
- **Right pane (60%)**: File tree and code viewer with optional diff view

This layout is activated when `screenWidth > 1400px` and file history is available.

---

## CLI Arguments

```bash
node cli.js <input-file> [options]

Options:
  --username <name>           Display name for user messages (default: "User")
  --format <html|markdown>    Output format (default: "html")
  --output <file>             Output file path
  --screenWidth <pixels>      Target screen width (default: 1200)
  --fileHistoryPath <path>    Path to ~/.claude/file-history
  --showDiffs                 Show side-by-side diffs instead of final files
```

### Example Commands

**Standard view with files:**
```bash
node cli.js session.jsonl --username JeffB --screenWidth 1728 \
  --fileHistoryPath ~/.claude/file-history
```

**Diff view:**
```bash
node cli.js session.jsonl --username JeffB --screenWidth 1728 \
  --fileHistoryPath ~/.claude/file-history --showDiffs
```

---

## File History Integration

### Data Source

Claude Code stores file history in `~/.claude/file-history/{sessionId}/`:
- Files named `{hash}@v{version}` (e.g., `abc123@v1`, `abc123@v2`)
- Each version is a complete file snapshot
- Linked to transcript via `file-history-snapshot` records

### File History Snapshot Record

From the transcript JSONL:
```json
{
  "type": "file-history-snapshot",
  "snapshot": {
    "trackedFileBackups": {
      "path/to/file.ts": {
        "backupFileName": "abc123@v2",
        "version": 2,
        "backupTime": "2025-11-18T19:27:46.419Z"
      }
    }
  }
}
```

### Loading Strategy

1. **Final version only** (default): Load highest version of each file
2. **All versions** (for diffs): Load v1 through vN for each file

```typescript
function loadFileVersions(fileHistory, sessionId, fileHistoryPath): Map<string, FileVersions>
```

---

## Diff Algorithm

### LCS-Based Approach

The diff uses Longest Common Subsequence (LCS) algorithm:

1. Split both files into lines
2. Compute LCS to find unchanged lines
3. Lines in LCS = unchanged (same)
4. Lines only in old = removed
5. Lines only in new = added

### Diff Line Types

```typescript
type DiffLine = {
  type: 'same' | 'added' | 'removed';
  oldLineNum?: number;
  newLineNum?: number;
  content: string;
};
```

### Side-by-Side Rendering

- **Same lines**: Show on both sides with matching line numbers
- **Removed lines**: Show on left with red background, empty placeholder on right
- **Added lines**: Empty placeholder on left, show on right with green background

---

## File Tree Generation

### Tree Building

```typescript
type TreeNode = {
  name: string;
  path: string;
  isFile: boolean;
  children: Map<string, TreeNode>;
  fileIndex?: number;
};
```

1. Parse file paths into tree structure
2. Sort: folders first, then files, alphabetically
3. Render recursively with proper indentation

### File Icons

Based on extension:
- `.ts`, `.tsx` → 📘
- `.js`, `.jsx` → 📒
- `.json` → 📋
- `.md` → 📄
- `.sql` → 🗃️
- `.css` → 🎨
- `.html` → 🌐
- Default → 📄

### Indentation

- 12px per depth level
- No extra padding in `.tree-folder-children` (handled by inline styles)
- `white-space: nowrap` prevents text wrapping

---

## JavaScript Interactions

### File Selection

```javascript
treeFiles.forEach(function(file) {
  file.addEventListener('click', function() {
    // Update active state in tree
    // Show corresponding file content
    // Update header with file path
  });
});
```

### Folder Toggle

```javascript
folderHeaders.forEach(function(header) {
  header.addEventListener('click', function() {
    // Toggle children visibility
    // Swap folder icon (📂 ↔ 📁)
  });
});
```

---

## Color Scheme

VS Code-inspired dark theme:

| Element | Color |
|---------|-------|
| Background | `#1e1e1e` |
| Pane background | `#252526` |
| Header background | `#2d2d2d` |
| Text | `#e8e6e3` |
| Muted text | `#808080` |
| User accent | `#4ec9b0` (teal) |
| Claude accent | `#ce9178` (orange) |
| Header text | `#569cd6` (blue) |
| Added lines | `#89d185` / `rgba(35,134,54,0.2)` |
| Removed lines | `#f48771` / `rgba(248,81,73,0.2)` |
| Active file | `#094771` |

---

## Responsive Behavior

### Screen Width Thresholds

- `> 1400px`: Two-pane layout with file viewer
- `≤ 1400px`: Single-pane conversation only

### Single Pane Fallback

```css
body.single-pane {
  max-width: 1200px;
  margin: 0 auto;
}
```

---

## Future Improvements

### Toggle Between Views
- Add UI toggle to switch between Final and Diff views without regenerating

### Version Navigation
- Dropdown to select which versions to compare (v1→v2, v2→v3, etc.)

### Synchronized Scrolling
- Link scroll position between conversation and file viewer
- Highlight file when Claude mentions editing it

### Syntax Highlighting
- Integrate Prism.js or highlight.js for language-aware coloring

### Search
- Find in conversation
- Find in files

# Transcript Parsing: Complete Reference

This document captures everything learned during the development of the Claude Code transcript parser. It serves as both technical documentation and historical record of design decisions, challenges, and solutions.

---

## Overview & Purpose

### What It Does

The transcript parser converts Claude Code session transcripts (JSONL format) into human-readable HTML and Markdown files suitable for display on a website. It transforms raw conversation logs into polished, interactive web pages that showcase coding sessions with Claude.

### Why We Built It

The coding-with-claude project aims to create a website showcasing real development sessions with Claude Code. These sessions demonstrate how AI-assisted development works in practice, providing valuable learning material for developers interested in AI pair programming.

### Output Formats

- **HTML (Primary)**: Interactive web pages with terminal-style dark theme, collapsible sections, and markdown rendering
- **Markdown (Secondary)**: Plain markdown files for simpler viewing or further processing

---

## JSONL Transcript Format

### File Structure

Claude Code generates transcript files in JSONL (JSON Lines) format - one JSON object per line, with each line representing a discrete event in the conversation.

### Naming Conventions

- **Main sessions**: `{uuid}.jsonl` (e.g., `7e6a848a-f0e0-4a10-83e0-495e287003f8.jsonl`)
- **Agent sessions**: `agent-{short-id}.jsonl` (e.g., `agent-0863aa61.jsonl`)
- Main sessions are the primary conversation; agent sessions are background tasks

### Record Types

Each line in the JSONL file is one of these record types:

1. **User message** (`type: "user"`)
   - Contains user input text
   - May contain tool results from previous assistant tool calls
   - Has `isMeta` flag for system-generated messages

2. **Assistant message** (`type: "assistant"`)
   - Contains Claude's response
   - May include thinking, text, and tool_use content
   - Includes token usage statistics

3. **Summary** (`type: "summary"`)
   - Generated when conversation is condensed
   - Contains natural language summary of session

4. **Tool results**
   - Embedded in user messages as `tool_result` content
   - Links to preceding tool_use via `tool_use_id`
   - Has `is_error` flag for error states

### Content Structure

Messages contain arrays of content blocks:

- **text**: Plain text from user or assistant
- **thinking**: Claude's internal reasoning (shown with 💭 toggle)
- **tool_use**: Function call with name, id, and input parameters
- **tool_result**: Output from tool execution, linked by id

---

## Technical Architecture

### The Two-Pass Parsing Algorithm

The parser uses a two-pass algorithm to correctly attribute tool results:

#### Why Two Passes?

In raw transcripts, tool results appear in subsequent user messages (because that's how the API works), but they're actually outputs from Claude's tool calls. This creates a confusing attribution problem where tool outputs appear to come from the user.

#### How It Works

**First Pass: Collect Tool Results**
```typescript
const toolResults = new Map<string, ParsedContent>();

for (const record of records) {
  if (record.type === 'user') {
    const content = record.message.content;
    if (Array.isArray(content)) {
      for (const item of content) {
        if (item.type === 'tool_result') {
          toolResults.set(item.tool_use_id, {
            type: 'tool_result',
            toolUseId: item.tool_use_id,
            content: item.content,
            isError: item.is_error,
          });
        }
      }
    }
  }
}
```

**Second Pass: Integrate Results with Assistant Messages**
```typescript
for (const record of records) {
  if (record.type === 'assistant') {
    const assistantMessage = parseAssistantMessage(record);
    const contentWithResults: ParsedContent[] = [];

    for (const content of assistantMessage.content) {
      contentWithResults.push(content);
      // If this is a tool_use, add its result right after it
      if (content.type === 'tool_use') {
        const result = toolResults.get(content.id);
        if (result) {
          contentWithResults.push(result);
        }
      }
    }

    assistantMessage.content = contentWithResults;
    messages.push(assistantMessage);
  }
}
```

This ensures tool results appear immediately after their corresponding tool calls, under Claude's messages where they belong.

### Message Merging Strategy

Consecutive messages from the same role are merged to reduce clutter and improve readability.

#### Why Merge?

Raw transcripts can have many consecutive assistant messages as Claude works through a problem step-by-step. Without merging, a single conceptual interaction might span dozens of message blocks.

#### Results

- Session with 564 raw messages → 24 merged messages
- Session with 66 raw messages → 20 merged messages
- Dramatic reduction in visual noise

#### Token Usage Handling

When merging messages, token usage is summed:
```typescript
const mergedTokenUsage: TokenUsage = {
  input_tokens: current.tokenUsage.input_tokens + next.tokenUsage.input_tokens,
  output_tokens: current.tokenUsage.output_tokens + next.tokenUsage.output_tokens,
  cache_read_input_tokens:
    (current.tokenUsage.cache_read_input_tokens || 0) +
    (next.tokenUsage.cache_read_input_tokens || 0),
  cache_creation_input_tokens:
    (current.tokenUsage.cache_creation_input_tokens || 0) +
    (next.tokenUsage.cache_creation_input_tokens || 0),
};
```

### Meta and Command Message Filtering

System-generated messages are filtered out to keep transcripts clean.

#### What Gets Filtered

1. **Meta messages**: Messages with `isMeta: true` flag
2. **Command messages**: Messages containing XML tags like:
   - `<command-name>`
   - `<command-message>`
   - `<local-command-stdout>`
   - `<local-command-stderr>`
3. **Tool-result-only messages**: User messages containing only tool results (no actual user text)

#### Implementation

```typescript
function isCommandMessage(record: UserMessageRecord): boolean {
  const content = record.message.content;
  if (typeof content === 'string') {
    return (
      content.includes('<command-name>') ||
      content.includes('<command-message>') ||
      content.includes('<local-command-stdout>') ||
      content.includes('<local-command-stderr>')
    );
  }
  return false;
}

function isOnlyToolResults(record: UserMessageRecord): boolean {
  const content = record.message.content;
  if (Array.isArray(content)) {
    return content.length > 0 && content.every((item) => item.type === 'tool_result');
  }
  return false;
}
```

### Markdown-to-HTML Conversion

Claude's text responses often contain markdown formatting. The parser converts this to proper HTML.

#### Supported Features

- **Headers**: `## Text` → `<h2>Text</h2>`
- **Bold**: `**text**` → `<strong>text</strong>`
- **Italic**: `*text*` → `<em>text</em>`
- **Inline code**: `` `code` `` → `<code>code</code>`
- **Unordered lists**: `- item` → `<ul><li>item</li></ul>`
- **Ordered lists**: `1. item` → `<ol><li>item</li></ol>`

#### Implementation Details

The converter processes text line-by-line:

```typescript
function convertMarkdownToHtml(markdown: string): string {
  let html = markdown;
  const lines = html.split('\n');
  const processedLines: string[] = [];
  let inList = false;
  let listType: 'ul' | 'ol' | null = null;

  for (let i = 0; i < lines.length; i++) {
    const line = lines[i];
    if (!line && line !== '') continue;

    // Headers
    const headerMatch = line.match(/^(#{1,6})\s+(.+)$/);
    if (headerMatch && headerMatch[1] && headerMatch[2]) {
      const level = headerMatch[1].length;
      const content = escapeHtml(headerMatch[2]);
      const processedContent = processInlineMarkdown(content);
      processedLines.push(`<h${level}>${processedContent}</h${level}>`);
      continue;
    }

    // Lists and other processing...
  }

  return processedLines.join('<br>');
}
```

Inline formatting is handled separately:

```typescript
function processInlineMarkdown(text: string): string {
  let processed = text;
  processed = processed.replace(/`([^`]+)`/g, '<code>$1</code>');
  processed = processed.replace(/\*\*([^*]+)\*\*/g, '<strong>$1</strong>');
  processed = processed.replace(/\*([^*]+)\*/g, '<em>$1</em>');
  return processed;
}
```

### Path Stripping

Personal file paths are stripped for privacy.

#### What Gets Stripped

The prefix `/Users/jeffbazinet/coding-with-claude/source/` is removed from all file paths in tool invocations.

#### Result

`/Users/jeffbazinet/coding-with-claude/source/coding-with-claude-application/CLAUDE.md`
becomes
`coding-with-claude-application/CLAUDE.md`

#### Implementation

```typescript
function stripPathPrefix(path: string): string {
  const prefix = '/Users/jeffbazinet/coding-with-claude/source/';
  if (path.startsWith(prefix)) {
    return path.slice(prefix.length);
  }
  return path;
}
```

Applied to Read, Edit, Write, Glob, and Grep tool calls.

### Smart Tool Display

Tool invocations show only relevant information, not verbose JSON.

#### Before
```json
{
  "command": "node --version",
  "description": "Check Node.js version",
  "timeout": 120000
}
```

#### After
```
🔧 Check Node.js version
node --version
```

#### Implementation

```typescript
function formatToolUse(toolUse: ToolUseContent): string {
  const description = typeof toolUse.input['description'] === 'string'
    ? toolUse.input['description']
    : `Tool: ${toolUse.name}`;

  if (toolUse.name === 'Bash' && typeof toolUse.input['command'] === 'string') {
    return `<div class="tool-use">
      <div class="tool-header">🔧 ${escapeHtml(description)}</div>
      <pre>${escapeHtml(toolUse.input['command'])}</pre>
    </div>`;
  }

  // Other tool-specific formatting...
}
```

### Terminal-Style Theme

The HTML output uses a VS Code-inspired dark theme:

- **Background**: `#1e1e1e` (dark gray)
- **Text**: `#e8e6e3` (light gray)
- **User messages**: `#4ec9b0` (teal) border
- **Assistant messages**: `#ce9178` (orange) border
- **Headers**: `#569cd6` (blue)
- **Code**: `#ce9178` (orange) on `#1e1e1e` background
- **Tool results**: `#4fc1ff` (cyan) border

---

## Design Decisions

### Why Two-Pass Parsing?

**Problem**: Tool results appear in user messages in raw transcripts, but they're actually outputs from Claude's tool calls.

**Solution**: Collect all tool results first, then integrate them with their corresponding tool_use calls in assistant messages.

**Alternative Considered**: Single-pass with lookahead. Rejected because it's more complex and harder to maintain.

### Why Merge Consecutive Messages?

**Problem**: Raw transcripts have many small messages, creating visual noise and making conversations hard to follow.

**Solution**: Merge consecutive messages from the same role into single message blocks.

**Benefit**: 564 messages → 24 messages in one session. Dramatically improved readability.

### Why Hide Tool Results by Default?

**Problem**: Tool outputs (especially large file reads or error messages) dominate the screen and obscure the actual conversation.

**Solution**: Hide results by default with toggle controls.

**User Experience**: Readers see the flow of conversation but can expand tool details when interested.

### Why Strip File Paths?

**Problem**: Full file paths reveal personal directory structure.

**Solution**: Strip common prefix from all file paths.

**Privacy Benefit**: Paths like `/Users/jeffbazinet/coding-with-claude/source/...` become `coding-with-claude-application/...`

### CSS Styling Choices

#### Dark Terminal Theme

**Rationale**: Matches the actual Claude Code terminal experience. Developers are familiar with dark themes.

#### Color Coding

- **Teal for user**: Distinguishes user input
- **Orange for assistant**: Distinguishes Claude's responses
- **Blue for headers**: Provides visual hierarchy
- **Monospace for code**: Maintains formatting and readability

#### Spacing and Typography

- **Line height 1.6**: Improves readability
- **Max-width 1200px**: Prevents lines from being too long
- **Padding and margins**: Creates visual breathing room

---

## Markdown Conversion Details

### Supported Markdown Features

The parser handles a subset of markdown that Claude commonly uses in responses.

#### Headers (h1-h6)

Pattern: `^(#{1,6})\s+(.+)$`

- `## Heading` → `<h2>Heading</h2>`
- Font sizes: h2 (20px), h3 (18px), h4 (16px), h5 (15px), h6 (14px)
- Color: `#569cd6` (blue)

#### Lists

**Unordered**: Pattern `^[-*]\s+(.+)$`
- `- Item` → `<ul><li>Item</li></ul>`
- `* Item` → `<ul><li>Item</li></ul>`

**Ordered**: Pattern `^\d+\.\s+(.+)$`
- `1. Item` → `<ol><li>item</li></ol>`
- Automatic numbering by browser

Lists properly nest and close when non-list content is encountered.

#### Inline Formatting

**Bold**: `\*\*([^*]+)\*\*` → `<strong>$1</strong>`
**Italic**: `\*([^*]+)\*` → `<em>$1</em>`
**Code**: `` `([^`]+)` `` → `<code>$1</code>`

### HTML Escaping

All user-provided content is HTML-escaped to prevent XSS:

```typescript
function escapeHtml(text: string): string {
  return text
    .replace(/&/g, '&amp;')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;')
    .replace(/"/g, '&quot;')
    .replace(/'/g, '&#039;');
}
```

Escaping happens before markdown processing, then markdown generates safe HTML tags.

### Line-by-Line Processing

The algorithm processes text line by line to handle block-level elements:

1. Check for headers
2. Check for list items
3. Track list state (in list? which type?)
4. Close lists when encountering non-list content
5. Apply inline formatting to all content

This approach handles mixed content correctly:
```
## Header
Some text
1. List item
2. Another item
More text
```

### Block vs Inline Elements

- **Block elements** (headers, lists) generate proper HTML tags
- **Inline elements** (bold, italic, code) are processed within text
- Block elements have proper margins and spacing
- Inline elements are styled but don't break flow

---

## Challenges & Solutions

### Challenge 1: Tool Result Attribution

**Problem**: Tool results were appearing under "👤 JeffB" headers when they were actually outputs from Claude's tool calls.

**Why It Happened**: In the raw API format, tool results come in subsequent user messages (as required by the API), but they're actually responses to Claude's tool invocations.

**Solution**: Two-pass parsing algorithm that:
1. Collects all tool results in first pass
2. Integrates them with their corresponding tool_use calls in assistant messages
3. Filters out user messages that contain only tool results

**Result**: Tool results now correctly appear under Claude's messages, immediately after the tool invocation.

### Challenge 2: Message Explosion

**Problem**: Sessions with hundreds of small messages were difficult to read and navigate.

**Example**: One session had 564 individual message records.

**Solution**: Merge consecutive messages from the same role into single message blocks.

**Implementation**: Track current message, compare role with next message, merge content if same role.

**Result**: 564 messages → 24 merged messages. Much cleaner and easier to follow.

### Challenge 3: System Noise

**Problem**: Login commands, meta messages, and command XML tags appearing in transcripts.

**Example**: `<command-name>/login</command-name>` and `<local-command-stdout>` tags in first message.

**Solution**: Filter messages based on:
- `isMeta` flag
- Presence of command XML tags
- Messages containing only tool results (no user text)

**Result**: Clean transcripts showing only meaningful conversation content.

### Challenge 4: Raw Markdown Display

**Problem**: Claude's responses containing markdown (headers, lists, bold text) displayed as raw markdown instead of formatted HTML.

**Example**: `## What's Strong ✓` appearing literally instead of as a styled header.

**Solution**: Implemented `convertMarkdownToHtml()` function that:
- Parses headers, lists, and inline formatting
- Generates proper HTML elements
- Preserves line breaks with `<br>` tags
- Applies inline formatting within text

**Result**: Claude's responses now display with proper formatting, headers, lists, and text styling.

### Challenge 5: TypeScript Strict Mode

**Problem**: TypeScript strict mode with `exactOptionalPropertyTypes: true` caught many potential runtime errors.

**Example**: `Type 'undefined' is not assignable to type 'TokenUsage'`

**Solution**: Use conditional spread operator for optional properties:
```typescript
return {
  uuid: current.uuid,
  role: current.role,
  content: [...current.content, ...next.content],
  ...(mergedTokenUsage && { tokenUsage: mergedTokenUsage }),
};
```

**Result**: Type-safe code that handles undefined values correctly.

### Challenge 6: CSS for Markdown Elements

**Problem**: After converting markdown to HTML, elements had no styling (headers, lists all looked the same).

**Solution**: Added comprehensive CSS for markdown-converted elements:
- Headers with proper sizing and color
- Lists with indentation and bullet points
- Inline code with background and padding
- Strong and em tags with appropriate styling

**Result**: Formatted content looks polished and professional.

## Usage & CLI

### Command-Line Arguments

```bash
node dist/cli.js <input-file> [options]
```

**Arguments:**
- `<input-file>`: Path to JSONL transcript file (required)
- `--username <name>`: Display name for user messages (default: "User")
- `--format <format>`: Output format: "html" or "markdown" (default: "html")
- `--output <file>`: Output file path (optional, auto-generated if not specified)

### Example Commands

**Generate HTML with custom username:**
```bash
node dist/cli.js transcripts/session.jsonl --username JeffB --format html
```

**Generate markdown:**
```bash
node dist/cli.js transcripts/session.jsonl --format markdown
```

**Specify output file:**
```bash
node dist/cli.js transcripts/session.jsonl --output output/session.html
```

### Output File Naming

If `--output` is not specified, output filename is auto-generated from session timestamp:

**Pattern:** `YYYY-MM-DD_HH-MM-SS_session.{html|md}`

**Example:** `2025-11-17_13-51-32_session.html`

The timestamp is extracted from the `startTimestamp` field in the first message of the session.

### Processing Multiple Files

**Bash loop to process all main session files:**
```bash
for file in transcripts/*.jsonl; do
  [[ ! "$file" =~ agent ]] && \
  node dist/cli.js "$file" --username JeffB --format html
done
```

This processes all `.jsonl` files except agent sessions.

## Lessons Learned

### Start with Data Structure Understanding

**Lesson**: Before writing any code, thoroughly understand the input data structure.

**Application**: We spent time analyzing JSONL format, record types, and content structure. This foundation made implementation smoother and helped avoid refactoring.

### Plan for Interactive Features Early

**Lesson**: Interactive features (toggles, collapsible sections) should be planned from the start, not bolted on later.

**Application**: We added thinking toggle early, then later added tool result toggles. If planned together initially, the code would have been cleaner.

### Privacy Considerations

**Lesson**: Transcripts contain personal information (file paths, usernames) that should be scrubbed.

**Application**: Path stripping was added mid-development. Should have been identified in initial planning.

**Recommendation**: Always consider privacy before displaying any user-generated content.

### Performance Implications

**Lesson**: Message merging dramatically reduced DOM size and improved rendering performance.

**Application**: 564 messages → 24 messages = much faster page load and rendering.

**Recommendation**: Consider performance impact of data structure choices early.

### CSS Scoping is Critical

**Lesson**: Markdown-converted HTML elements need scoped CSS to avoid affecting other page elements.

**Application**: All markdown element styles are scoped to `.message-content` to prevent interference.

**Recommendation**: Always scope generated HTML styling to avoid conflicts.

### Two-Pass Algorithms for Data Transformation

**Lesson**: Some transformations require multiple passes over data to establish context.

**Application**: Tool result attribution required collecting all results before integration.

**Recommendation**: Don't force single-pass solutions when two-pass is clearer and more maintainable.

### Type Safety Catches Bugs Early

**Lesson**: TypeScript strict mode catches potential runtime errors during development.

**Application**: `exactOptionalPropertyTypes: true` caught undefined access issues before they became runtime bugs.

**Recommendation**: Use strict TypeScript settings from project start.

### User Feedback Drives Iteration

**Lesson**: The best improvements came from actually looking at generated output and identifying issues.

**Application**:
- "Tool results under wrong user" → Two-pass parsing
- "Too many messages" → Message merging
- "Raw markdown showing" → Markdown conversion
- "Personal file paths" → Path stripping

**Recommendation**: Generate real output early and review it like an end user would.

### Documentation as You Go

**Lesson**: Documenting decisions and challenges in real-time is much easier than reconstructing later.

**Application**: This document captures details that would be forgotten if written months later.

**Recommendation**: Keep notes during development, not just after completion.

     1→# CLAUDE.md
     2→
     3→This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
     4→
     5→---
     6→
     7→## CRITICAL: Role and Professional Standards
     8→
     9→**Claude Code's role on this project is to serve as a "highly experienced senior software engineer and application architect" with "in-depth understanding of the CWC codebase, conventions, and rules."**
    10→
    11→It is assumed, and imperative, that as a senior engineer, you will do your due diligence:
    12→
    13→### Required Due Diligence for Every Task
    14→
    15→**Before proposing any design, architecture, or implementation:**
    16→
    17→1. **Read all relevant package CLAUDE.md files**
    18→   - If touching database → read `packages/cwc-database/CLAUDE.md`
    19→   - If defining/modifying types → read `packages/cwc-types/CLAUDE.md`
    20→   - If working with any package → read that package's CLAUDE.md file
    21→   - Package-specific conventions MUST be followed
    22→
    23→2. **Examine existing code in all affected packages**
    24→   - Check for existing types, schemas, or utilities before proposing new ones
    25→   - Understand established patterns and conventions
    26→   - Identify dependencies between packages
    27→
    28→3. **Understand the full scope**
    29→   - Identify all packages affected by the feature or change
    30→   - Consider both direct changes and indirect impacts (shared types, utilities, etc.)
    31→   - Plan across package boundaries, not in isolation
    32→
    33→4. **If the package needs .env configuration → integrate with cwc-configuration-helper**
    34→   - Read `packages/cwc-configuration-helper/CLAUDE.md` and `configuration.ts`
    35→   - Check `RuntimeConfigValues` for existing config values to reuse
    36→   - Use standard naming conventions (see "Configuration Value Naming Conventions")
    37→   - NEVER create manual sample.env files
    38→   - Determine what belongs in config vs CLI arguments
    39→
    40→### Cross-Package Feature Planning
    41→
    42→When working on features that span multiple packages:
    43→
    44→1. **Discovery phase first** - Survey the landscape before designing
    45→2. **Read documentation** - All relevant package CLAUDE.md files
    46→3. **Examine existing implementations** - Check for related code/patterns
    47→4. **Design within constraints** - Follow established conventions
    48→5. **Present context with design** - Show what you reviewed and how your design follows patterns
    49→
    50→**This is not optional.** The developer should not have to repeatedly point out missed conventions or overlooked existing code. Professional engineers build on institutional knowledge rather than reinventing or contradicting established patterns.
    51→
    52→### CRITICAL: Refactoring Discipline
    53→
    54→**When refactoring code, preserve original behavior exactly.** This is a fundamental software engineering principle:
    55→
    56→1. **Commented-out code stays commented out** - If code was commented out in the original, keep it commented in the refactored version. Do not inadvertently "resurrect" disabled functionality.
    57→
    58→2. **Preserve behavior not explicitly discussed** - When refactoring or restructuring code, any behavior that was not explicitly discussed as changing should be preserved exactly. Only modify what was specifically requested.
    59→
    60→3. **Configuration and infrastructure changes require extra care** - When modifying nginx configs, deployment scripts, or other infrastructure code, verify that all existing functionality is preserved. Missing a server block or location directive can break production.
    61→
    62→4. **Review before and after** - Before completing a refactor, compare the original and new versions to ensure nothing was lost or inadvertently added.
    63→
    64→5. **When in doubt, keep it** - If you're unsure whether something is needed, preserve it. It's safer to keep unused code than to accidentally remove required functionality.
    65→
    66→**This applies to all code changes, not just explicit refactoring tasks.** Even when adding new features or fixing bugs, ensure existing functionality remains intact.

   168→## Project Overview
   169→
   170→### What is codingwithclaude?
   171→
   172→A multi-tenant developer publishing platform: a dynamic, real-time publishing platform that serves as both a public feed for developer content and a private dashboard for external developers (users of the app) to manage and publish their own technical blog posts, organized by "Projects."
   173→
   174→### Project name & aliases
   175→
   176→In this document and prompts from the developer, all of these names or phrases are assumed to refer to the `project`:
   177→
   178→- `coding-with-claude`
   179→- `codingwithclaude`
   180→- `coding-with-claude`
   181→- `CWC` or `cwc`
   182→
   183→## Proactive Documentation Philosophy
   184→
   185→**CRITICAL: This file is a living knowledge base that must be continuously updated.**
   186→
   187→As Claude Code works with the developer, it is **EXPECTED** to proactively capture all learnings, patterns, critical instructions, and feedback in this CLAUDE.md file **WITHOUT being reminded**. This is a professional partnership where:
   188→
   189→- **Every gap discovered during planning or analysis** → Document the pattern to prevent future occurrences
   190→- **Every critical instruction from the developer** → Add to relevant sections immediately
   191→- **Every "I forgot to do X" moment** → Create a checklist or rule to prevent repetition
   192→- **Every architectural pattern learned** → Document it for consistency
   193→- **Every planning session insight** → Capture the learning before implementation begins
   194→
   195→**When to update CLAUDE.md:**
   196→
   197→1. **DURING planning sessions** - This is where most learning happens through analysis, feedback, and corrections
   198→2. **After receiving critical feedback** - Document the expectation immediately
   199→3. **After discovering a bug or oversight** - Add checks/rules to prevent it
   200→4. **After analysis reveals gaps** - Document what to check in the future
   201→5. **When the developer explains "this is how we do X"** - Add it to the guide
   202→6. **After implementing a new feature** - Capture any additional patterns discovered during execution
   203→
   204→**Planning sessions are especially critical:** The analysis, feedback, and corrections that happen during planning contain the most valuable learnings. Update CLAUDE.md with these insights BEFORE starting implementation, not after.
   205→
   206→**Professional expectation:** The developer should not need to repeatedly point out the same oversights or remind Claude Code to document learnings. Like professional teammates, we learn from each interaction and build institutional knowledge.
   207→
   208→**Format:** When updating this file, maintain clear structure, provide code examples where helpful, and organize related concepts together. Focus exclusively on information that helps Claude Code operate effectively during AI-assisted coding sessions.
   209→
   210→**Package-Specific Documentation:** When learning package-specific patterns, update the appropriate package CLAUDE.md file, not this root file.
   211→
   212→### CLAUDE.md File Specification
   213→
   214→**Purpose:** CLAUDE.md files are memory files for AI assistants (like Claude Code), NOT documentation for human developers.
   215→
   216→**What CLAUDE.md IS for:**
   217→
   218→- Architectural patterns and critical design decisions
   219→- Code conventions, naming rules, and style preferences
   220→- What to check during planning sessions
   221→- Lessons learned and mistakes to avoid
   222→- Project-specific security rules and compliance requirements
   223→- Critical implementation patterns that must be followed
   224→- "If you see X, always do Y" type rules
   225→- Checklists for common operations
   226→
   227→**What CLAUDE.md is NOT for (belongs in README.md):**
   228→
   229→- API documentation and endpoint specifications
   230→- Usage examples and tutorials for humans
   231→- Setup and installation instructions
   232→- General explanations and marketing copy
   233→- Step-by-step guides and how-tos
   234→- Detailed configuration walkthroughs
   235→- Complete type definitions (already in code)
   236→- Performance tuning guides for users
   237→
   238→**File Size Targets:**
   239→
   240→- **Warning threshold:** 40,000 characters per file (Claude Code performance degrades)
   241→- **Recommended:** Keep under 500 lines when possible for fast loading
   242→- **Best practice:** If a package CLAUDE.md approaches 300-400 lines, review for README-style content
   243→- **For large packages:** Use concise bullet points; move examples to README
   244→
   245→**Content Guidelines:**
   246→
   247→- **Be specific and actionable:** "Use 2-space indentation" not "Format code properly"
   248→- **Focus on patterns:** Show the pattern, explain when to use it
   249→- **Include context for decisions:** Why this approach, not alternatives
   250→- **Use code examples sparingly:** Only when pattern is complex
   251→- **Keep it scannable:** Bullet points and clear headers
   252→
   253→**CLAUDE.md vs README.md:**
   254→| CLAUDE.md | README.md |
   255→|-----------|-----------|
   256→| For AI assistants | For human developers |
   257→| Patterns and rules | Complete documentation |
   258→| What to check/avoid | How to use and setup |
   259→| Concise and focused | Comprehensive and detailed |
   260→| Loaded on every session | Read when needed |
   261→
   262→### Documentation Organization in Monorepos
   263→
   264→**Critical learnings about Claude Code documentation structure:**
   265→
   266→1. **Claude Code automatically loads all CLAUDE.md files recursively:**
   267→   - Reads CLAUDE.md in current working directory
   268→   - Recurses upward to parent directories (stops at workspace root)
   269→   - Discovers nested CLAUDE.md files in subdirectories
   270→   - All files are loaded together - they complement, not replace each other
   271→
   272→2. **Package-specific CLAUDE.md is the standard pattern for monorepos:**
   273→   - Root CLAUDE.md contains monorepo-wide conventions (tooling, git workflow, shared patterns)
   274→   - Package CLAUDE.md contains package-specific patterns (database schema, deployment, type generation)
   275→   - Working from any directory loads both root and relevant package docs automatically
   276→
   277→3. **Performance limit: 40,000 characters per file:**
   278→   - Claude Code shows performance warning when CLAUDE.md exceeds 40k characters
   279→   - Solution: Split into package-specific files, not multiple files in `.claude/` directory
   280→   - Only CLAUDE.md files are automatically loaded; other `.md` files in `.claude/` are NOT
   281→
   282→4. **Optimize for AI-assisted coding, not human readers:**
   283→   - Include patterns, conventions, code examples, and strict rules
   284→   - Include "what to check during planning" and "lessons learned" sections
   285→   - Exclude content primarily for human developers (marketing copy, general explanations)
   286→   - Focus on actionable information needed during coding sessions
   287→
   288→**When to create package CLAUDE.md:**
   289→
   290→- Package has unique architectural patterns
   291→- Package has specific conventions (schema rules, deployment procedures)
   292→- Package has domain-specific knowledge (auth flows, type generation)
   293→- Package documentation would exceed ~500 lines in root file
   294→
   295→### Technical Debt Tracking
   296→
   297→**Technical debt, future improvements, and enhancement ideas are tracked in `./cwc-tech-debt.md`.**
   298→
   299→During planning and development sessions, when improvements or enhancements are identified but deferred to avoid scope creep:
   300→
   301→1. **Capture the idea immediately** in `cwc-tech-debt.md`
   302→2. **Include context** - session number, priority, effort level
   303→3. **Document current vs desired state** - what exists now, what should exist
   304→4. **Note the benefit** - why this matters
   305→
   306→**Examples of what to capture:**
   307→- Enhancements identified during planning (e.g., AI agent for sensitive data detection)
   308→- Better long-term solutions when implementing quick fixes
   309→- Patterns that could be improved across the codebase
   310→- Performance optimizations identified but not yet implemented
   311→
   312→**This prevents scope creep** while preserving valuable insights for future development work.
   313→
   314→## File Access Restrictions and Security Boundaries
   315→
   316→**Claude Code operates under strict file access restrictions to protect sensitive data:**
   317→
   318→### Workspace Boundaries
   319→
   320→- **Claude Code can ONLY access files within the monorepo root:** `./coding-with-claude`
   321→- No access to parent directories, system files, or files outside this workspace
   322→- This is enforced by Claude Code's security model
   323→
   324→### Prohibited File Access
   325→
   326→**Claude Code is explicitly blocked from reading or writing:**
   327→
   328→1. **Environment files:**
   329→   - `.env` files at any location
   330→   - `.env.*` files (e.g., `.env.local`, `.env.production`, `.env.dev`)
   331→   - `*.env` files (e.g., `prod.cwc-sql.env`, `dev.cwc-storage.env`, `test.cwc-app.env`)
   332→   - Any variation of environment configuration files
   333→
   334→2. **Secret and credential files:**
   335→   - Any directory named `secrets/`, `secret/`, or `private/`
   336→   - Any directory with `secret`, `secrets`, or `private` in its path
   337→   - Any file with `secret`, `secrets`, `private`, or `credentials` in its filename
   338→   - Service account JSON files (`service-account-*.json`)
   339→   - Firebase configuration files (`google-services.json`, `GoogleService-Info.plist`)
   340→   - Any file matching `*credentials*.json`
   341→
   342→3. **Rationale:**
   343→   - Prevents accidental exposure of API keys, database passwords, and authentication tokens
   344→   - Protects production credentials and service account keys
   345→   - Reduces risk of sensitive data being included in code examples or logs
   346→   - Enforces principle of least privilege
   347→
   348→These restrictions are enforced in `.claude/settings.json` and cannot be overridden during a session.
   349→
   350→### cwc-secrets Folder Structure Reference
   351→
   352→Since Claude Code cannot access the secrets folder, here is the structure for reference:
   353→
   354→```
   355→cwc-secrets/
   356→├── configuration-helper/
   357→│   ├── generated-files/          # Output from config-helper generate command
   358→│   │   └── {env}.cwc-{service}.env
   359→│   └── {env}-secrets.json        # Secret values per environment
   360→├── env/                          # Active .env files (copied from generated-files)
   361→│   └── {env}.cwc-{service}.env

   365→├── deployment/
   366→│   ├── servers.json              # Server configuration for cwc-deployment
   367→│   └── ssh-keys/                 # SSH keys for deployment

   371→└── storage-api-keys/
   372→    └── storage-api-keys.json     # API keys for cwc-storage
   373→```
   374→
   375→**Key directories:**
   376→- `env/` - Active .env files used by services
   377→- `configuration-helper/generated-files/` - Output from config-helper (copy to env/)
   378→- `sql-client-api-keys/` - PEM files for cwc-sql JWT authentication
   379→
   380→## Git Workflow
   381→
   382→**The developer handles all git operations manually.** Claude should:
   383→
   384→- Never initiate git commits, pushes, pulls, or any write operations
   385→- Only use git for read-only informational purposes (status, diff, log, show)
   386→- Not proactively suggest git operations unless explicitly asked
   387→
   388→Git write operations are blocked in `.claude/settings.json` to enforce this workflow.
   389→
   390→## Architecture Overview
   391→
   392→### Monorepo Structure
   393→
   394→- root project: `/coding-with-claude`
   395→- packages (apps, microservices, utilities):
   396→  - `cwc-types`: shared TypeScript types to be used in all other packages
   397→  - `cwc-utils`: shared utilities for browser and Node.js (profanity checking, validation helpers, etc.)
   398→  - `cwc-schema`: shared schema management library that may be used by frontend and backend packages
   399→  - `cwc-deployment`: isolated deployment CLI for database, services, nginx, website, and dashboard

   412→  - `cwc-admin-api`: the admin and data api used by the `cwc-dashboard` app
   413→  - `cwc-transcript-parser`: CLI tool for parsing Claude transcript JSONL files
   414→  - `cwc-e2e`: a set of end-to-end tests
   415→
   416→**Tech Stack:** to be determined as we build each package, update this documentation as we go.
   417→
   418→## Development Tooling & Infrastructure
   419→
   420→### Monorepo Management
   421→
   422→**pnpm v9.x + Turborepo v2.x**
   423→
   424→- **pnpm workspaces** for package management and dependency resolution
   425→  - Configured in `pnpm-workspace.yaml`
   426→  - Packages located in `packages/*`
   427→  - Uses content-addressable storage for disk efficiency
   428→  - Strict dependency resolution prevents phantom dependencies
   429→- **Turborepo** for task orchestration and caching
   430→  - Configured in `turbo.json`
   431→  - Intelligent parallel execution based on dependency graph
   432→  - Local caching for faster rebuilds
   433→  - Pipeline tasks: `build`, `dev`, `test`, `lint`, `typecheck`
   434→
   435→### Node.js Version
   436→
   437→- **Node.js 22 LTS** (specified in `.nvmrc`)
   438→- Required for all development and production environments
   439→- Use `nvm` for version management
   440→
   441→### Code Quality Tools
   442→
   443→**TypeScript v5.4+**
   444→
   445→- Configured in `tsconfig.base.json`
   446→- Strict mode enabled with enhanced type checking
   447→- JavaScript explicitly disallowed (`allowJs: false`)
   448→- Monorepo-optimized with composite projects
   449→- Individual packages extend base config
   450→
   451→**Module Resolution: bundler**
   452→
   453→- Uses `"moduleResolution": "bundler"` in tsconfig.base.json
   454→- Uses `"module": "ES2022"` (required for bundler resolution)
   455→- Allows clean TypeScript imports without `.js` extensions
   456→  - ✅ Correct: `import { Schema } from './types'`
   457→  - ❌ Not needed: `import { Schema } from './types.js'`
   458→- Still produces correct ES module output in compiled JavaScript
   459→- Designed for TypeScript projects compiled by tsc or bundlers
   460→
   461→**Why bundler over NodeNext:**
   462→
   463→- **Better DX:** No `.js` extensions in TypeScript source files
   464→- **Modern standard:** Industry standard for TypeScript libraries and monorepos
   465→- **Same output:** Still generates proper ES modules (.js files)
   466→- **No trade-offs:** Type safety and module compatibility maintained
   467→
   468→**Note:** Previously used `"moduleResolution": "NodeNext"` which required `.js` extensions per ES modules spec (e.g., `import './types.js'`). Switched to `bundler` in session 007 for cleaner imports across all packages.
   469→
   470→**ESLint v8.x with TypeScript**
   471→
   472→- Configured in `.eslintrc.json`
   473→- Uses `@typescript-eslint/strict` ruleset
   474→- Enforces explicit function return types
   475→- Prohibits `any` type and non-null assertions
   476→- Strict boolean expressions required
   477→
   478→**Prettier v3.x**
   479→
   480→- Configured in `.prettierrc.json`
   481→- Standards:
   482→  - Single quotes
   483→  - 2-space indentation
   484→  - 100 character line width
   485→  - Trailing commas (ES5)
   486→  - LF line endings
   487→
   488→### Root Scripts
   489→
   490→Run from monorepo root using `pnpm`:
   491→
   492→- `pnpm build` - Build all packages (parallel, cached)
   493→- `pnpm dev` - Run all packages in dev mode
   494→- `pnpm test` - Run tests across all packages (parallel, cached)
   495→- `pnpm lint` - Lint all packages (parallel, cached)
   496→- `pnpm typecheck` - Type-check all packages (parallel, cached)
   497→- `pnpm format` - Format all files with Prettier
   498→- `pnpm format:check` - Check formatting without changes
   499→
   500→### Development Workflow
   501→
   502→1. **Before starting work:**
   503→   - Ensure Node 22 is active: `nvm use`
   504→   - Install dependencies: `pnpm install`
   505→
   506→2. **During development:**
   507→   - Run dev mode: `pnpm dev` (in specific package or root)
   508→   - Format code: `pnpm format`
   509→
   510→3. **Before committing:**
   511→   - Type-check: `pnpm typecheck`
   512→   - Lint: `pnpm lint`
   513→   - Format check: `pnpm format:check`
   514→   - Run tests: `pnpm test`
   515→
   516→### Package Creation Conventions
   517→
   518→**When creating a new package in the monorepo:**
   519→
   520→1. **Version Number:** Always start new packages at version `1.0.0` (not `0.0.1`)
   521→   - Example: `"version": "1.0.0"` in package.json
   522→   - This is a project preference for consistency
   523→
   524→2. **Package Structure:**
   525→   - Follow existing package patterns (see cwc-types as reference)
   526→   - Include `package.json`, `tsconfig.json` extending base config
   527→   - Place source files in `src/` directory
   528→   - Include appropriate `build` and `typecheck` scripts
   529→
   530→3. **Package Entry Points (CRITICAL - bundler resolution):**
   531→   - Point `main`, `types`, and `exports` to `./src/index.ts` (NOT `./dist`)
   532→   - With `bundler` module resolution, we reference TypeScript source directly
   533→   - Example:
   534→     ```json
   535→     "main": "./src/index.ts",
   536→     "types": "./src/index.ts",
   537→     "exports": {
   538→       ".": {
   539→         "types": "./src/index.ts",
   540→         "default": "./src/index.ts"
   541→       }
   542→     }
   543→     ```
   544→   - ❌ NEVER use `./dist/index.js` or `./dist/index.d.ts`
   545→
   546→4. **Package Naming:**
   547→   - Use `cwc-` prefix for all CWC packages
   548→   - Use kebab-case: `cwc-types`, `cwc-backend-utils`, etc.
   549→
   550→5. **Package Documentation (Required for all packages):**
   551→   - **CLAUDE.md** - For AI-assisted coding:
   552→     - Create `packages/{package-name}/CLAUDE.md`
   553→     - Document architecture decisions, design patterns, and critical implementation details
   554→     - Keep focused on patterns, conventions, and rules for AI assistants
   555→   - **README.md** - For human developers:
   556→     - Create `packages/{package-name}/README.md`
   557→     - Include setup instructions, API documentation, usage examples
   558→     - Provide comprehensive documentation for developers using the package
   559→   - Both files should be created when a new package is built
   560→   - Update root CLAUDE.md "Package-Specific Documentation" section to list the new package
   561→
   562→6. **Add Package Shortcut Script:**
   563→   - Add a shortcut script to root `package.json` for the new package
   564→   - Format: `"package-name-shortcut": "pnpm --filter cwc-package-name"`
   565→   - Example: `"backend-utils": "pnpm --filter cwc-backend-utils"`
   566→   - This allows simplified commands: `pnpm backend-utils add express` instead of `pnpm --filter cwc-backend-utils add express`
   567→   - Keep shortcuts in alphabetical order in the scripts section
   568→
   569→## Key Architectural Decisions & Patterns
   570→
   571→### MariaDB Database
   572→
   573→1. Strong Schema Enforcement
   574→2. Transaction support
   575→3. Efficient Joins
   576→4. Data normalization
   577→5. Sophisticated Querying and Analytics
   578→
   579→**Details:** See `packages/cwc-database/CLAUDE.md` for complete database schema conventions.
   580→
   581→### PkId Naming Convention
   582→
   583→`PkId` stands for "Primary Key Id". All tables use this suffix for their auto-increment primary key:
   584→
   585→- `userPkId` = user primary key id
   586→- `projectPkId` = project primary key id
   587→- `codingSessionPkId` = coding session primary key id
   588→
   589→Foreign key references also use `PkId` suffix to indicate they reference a primary key (e.g., `userPkId` column in `project` table references `user.userPkId`).
   590→
   591→### TypeScript
   592→
   593→- Strict mode enabled (`strict: true`)
   594→- Shared types in `cwc-types` package; duplicating types in separate projects leads to inconsistencies, incompatibility, confusion, and extra work
   595→- Never use `any` - prefer `unknown` if type is truly unknown
   596→- Use string literal union types, not enums
   597→- Use `type` for entity definitions, not `interface`
   598→- **Use `undefined`, never `null`** - simplifies code by avoiding explicit checks for both values; aligns with TypeScript's optional property syntax (`field?: string`)
   599→- Run `typecheck` before committing
   600→
   601→**Details:** See `packages/cwc-types/CLAUDE.md` for complete TypeScript patterns and type generation.
   602→
   603→### Path Construction (Searchability)
   604→
   605→**Use concatenated path strings in `path.join()` for better searchability:**
   606→
   607→```typescript
   608→// ✅ GOOD - searchable for "deployment/servers.json"
   609→path.join(secretsPath, 'deployment/servers.json');
   610→
   611→// ❌ AVOID - searching for "deployment/servers.json" won't find this
   612→path.join(secretsPath, 'deployment', 'servers.json');
   613→```
   614→
   615→**Exception:** Directory navigation with `..` should remain segmented:
   616→
   617→```typescript
   618→// This is fine - navigating up directories
   619→path.join(__dirname, '..', '..', 'templates');
   620→```
   621→
   622→### Naming Conventions for Configuration Values
   623→
   624→**Clarity is critical for maintainability.** Configuration names should clearly indicate:
   625→
   626→1. **What** the value is for (its purpose)
   627→2. **Where** it's used (which service/context)
   628→
   629→**Examples:**
   630→
   631→- `sqlClientApiKey` - Clear: API key for SQL Client authentication
   632→- `authenticationPublicKey` - Unclear: Could apply to any auth system
   633→
   634→**Rule:** When naming configuration values, prefer verbose, descriptive names over short, ambiguous ones. When a developer returns to the code after weeks or months, the name should immediately convey the purpose without requiring investigation.
   635→
   636→**Package-specific prefixes:** When a configuration value is only used by one package, prefix it with the package context to avoid ambiguity:
   637→
   638→- `storageLogPath` / `STORAGE_LOG_PATH` - Clear: log path for cwc-storage
   639→- `logPath` / `LOG_PATH` - Unclear: which service uses this?
   640→- `contentCacheMaxSize` / `CONTENT_CACHE_MAX_SIZE` - Clear: cache setting for cwc-content
   641→- `cacheMaxSize` / `CACHE_MAX_SIZE` - Unclear: which service uses this cache?
   642→
   643→### Secret and API Key Generation
   644→
   645→**Use `crypto.randomBytes()` for generating secrets and API keys:**
   646→
   647→```typescript
   648→import crypto from 'crypto';
   649→
   650→// Generate a 256-bit (32-byte) cryptographically secure random key
   651→const apiKey = crypto.randomBytes(32).toString('hex'); // 64-character hex string
   652→```
   653→
   654→This produces cryptographically secure random values suitable for:
   655→
   656→- API keys (e.g., `STORAGE_API_KEY`)
   657→- JWT secrets (e.g., `USER_JWT_SECRET`)
   658→- Any symmetric secret requiring high entropy
   659→
   660→### Cloud-Agnostic Microservices
   661→
   662→CWC uses a microservices architecture deployed as Docker containers potentially deployed across multiple datacenters.
   663→
   664→1. Vendor lock-in is a real business risk. Cloud providers can change pricing, deny service access, or deprecate features at any time.
   665→2. Cloud-agnostic microservices architecture allows switching hosting providers with minimal effort.
   666→3. Preparation for Scale - can scale by adding infrastructure (more containers, load balancers) rather than rewriting code and specific services can be scaled based on actual load patterns
   667→
   668→### Environment Configuration
   669→
   670→**NODE_ENV vs RUNTIME_ENVIRONMENT:**
   671→
   672→| Variable              | Purpose                      | Set By         | Values                               |
   673→| --------------------- | ---------------------------- | -------------- | ------------------------------------ |
   674→| `NODE_ENV`            | Build-time behavior          | npm/bundlers   | `development`, `production`, `test`  |
   675→| `RUNTIME_ENVIRONMENT` | Application runtime behavior | CWC deployment | `dev`, `test`, `prod`, `unit`, `e2e` |
   676→
   677→**NODE_ENV (npm/Node.js ecosystem):**
   678→
   679→- Controls build optimizations (minification, tree-shaking)
   680→- Affects dependency installation behavior
   681→- CWC does NOT read this in application config
   682→
   683→**RUNTIME_ENVIRONMENT (CWC application):**
   684→
   685→- Controls application behavior (email sending, error verbosity, feature flags)
   686→- Type: `RuntimeEnvironment` from cwc-types
   687→- CWC config system reads this via `loadConfig()`
   688→
   689→**Rules:**
   690→
   691→- Test scripts: `RUNTIME_ENVIRONMENT=unit jest` (not `NODE_ENV=unit`)
   692→- Backend config: Always read `RUNTIME_ENVIRONMENT`, never `NODE_ENV`
   693→- Each package reads configuration from `.env` file tailored to the runtime environment
   694→
   695→**1-to-1 Naming Convention:**
   696→
   697→Use consistent naming across all runtime environment references for searchability and clarity:
   698→
   699→| Runtime Environment | Env File         | Config Flag | Mock Function            |
   700→| ------------------- | ---------------- | ----------- | ------------------------ |
   701→| `dev`               | `dev.cwc-*.env`  | `isDev`     | `createMockDevConfig()`  |
   702→| `prod`              | `prod.cwc-*.env` | `isProd`    | `createMockProdConfig()` |
   703→| `unit`              | `unit.cwc-*.env` | `isUnit`    | `createMockUnitConfig()` |
   704→| `e2e`               | `e2e.cwc-*.env`  | `isE2E`     | `createMockE2EConfig()`  |
   705→| `test`              | `test.cwc-*.env` | `isTest`    | `createMockTestConfig()` |
   706→
   707→This consistency enables searching for `Dev` or `Prod` to find all related code paths.
   708→
   709→### Configuration Values Are Code (CRITICAL)
   710→
   711→**IMPORTANT: In this project, configuration IS code. The .env files are generated artifacts, not manually edited files.**
   712→
   713→#### Mandatory cwc-configuration-helper Integration
   714→
   715→**RULE: Every package that needs .env configuration MUST integrate with cwc-configuration-helper.**
   716→
   717→This is non-negotiable. Never:
   718→- ❌ Create manual `sample.env` files
   719→- ❌ Hardcode configuration values that should come from environment
   720→- ❌ Invent new naming conventions for config values
   721→- ❌ Skip the configuration helper for "quick" implementations
   722→
   723→**When creating a new package that needs configuration:**
   724→
   725→1. **Add the service to ServiceName** in `packages/cwc-configuration-helper/src/configuration.ts`
   726→2. **Add config values to RuntimeConfigValues** for shared values across services
   727→3. **Define the config type** in the package's `config.types.ts`
   728→4. **Implement loadConfig()** following the cwc-backend-utils pattern
   729→5. **Generate .env files** using `pnpm config-helper run exec generate`
   730→6. **Never create sample.env** - the generated files ARE the samples
   731→
   732→**The configuration flow:**
   733→```
   734→config.types.ts (type definition)
   735→       ↓
   736→configuration.ts (actual values per environment)
   737→       ↓
   738→cwc-configuration-helper generate (tool)
   739→       ↓
   740→{env}.{package}.env (generated output)
   741→```
   742→
   743→#### Configuration Value Naming Conventions (CRITICAL)
   744→
   745→**Use standard names for shared configuration values.** When multiple packages use the same type of value, use identical naming:
   746→
   747→| Value Type | Standard Property Name | Standard Env Variable |
   748→|------------|----------------------|----------------------|
   749→| API service URL | `apiUriExternal` | `API_URI_EXTERNAL` |
   750→| Content service URL | `contentUriExternal` | `CONTENT_URI_EXTERNAL` |
   751→| Auth service URL | `authUriExternal` | `AUTH_URI_EXTERNAL` |
   752→| SQL service URL | `sqlUriInternal` | `SQL_URI_INTERNAL` |
   753→
   754→**❌ DO NOT invent alternate names:**
   755→- `apiBaseUri` → use `apiUriExternal`
   756→- `contentBaseUrl` → use `contentUriExternal`
   757→- `API_URL` → use `API_URI_EXTERNAL`
   758→
   759→**Package-specific config values** should be prefixed with the package context:
   760→
   761→| Package | Property Name | Env Variable |
   762→|---------|--------------|--------------|
   763→| cwc-storage | `storageVolumePath` | `STORAGE_VOLUME_PATH` |
   764→| cwc-content | `contentCacheMaxSize` | `CONTENT_CACHE_MAX_SIZE` |
   765→| cwc-sql | `sqlConnectionDebugMode` | `SQL_CONNECTION_DEBUG_MODE` |
   766→| cwc-session-importer | `sessionImporterProjectsPath` | `SESSION_IMPORTER_PROJECTS_PATH` |
   767→
   768→#### CLI Arguments vs Configuration
   769→
   770→**Not all values belong in .env files.** Use this decision framework:
   771→
   772→| Value Characteristic | Storage |
   773→|---------------------|---------|
   774→| Changes per environment (dev/test/prod) | .env via configuration-helper |
   775→| Changes per user/machine | .env via configuration-helper |
   776→| Stable infrastructure settings | .env via configuration-helper |
   777→| Changes frequently (expires, varies per operation) | CLI argument |
   778→| Sensitive per-request credentials | CLI argument |
   779→| User-specific tokens (JWT) | CLI argument |
   780→
   781→**Example:** For cwc-session-importer:
   782→- `sessionImporterProjectsPath` → .env (stable per machine)
   783→- `apiUriExternal` → .env (stable per environment)
   784→- `--jwt <token>` → CLI arg (expires every 15-30 min)
   785→- `--project-id <id>` → CLI arg (varies per operation)
   786→
   787→#### NEVER Provide Default Values for Required Configuration (CRITICAL)
   788→
   789→**RULE: Required configuration values must NEVER have fallback defaults in code.**
   790→
   791→```typescript
   792→// ❌ DANGEROUS - silently defaults to 'dev' if not set
   793→const runtimeEnv = process.env['RUNTIME_ENVIRONMENT'] || 'dev';
   794→
   795→// ❌ DANGEROUS - silently defaults to empty string
   796→const apiUri = process.env['API_URI_EXTERNAL'] ?? '';
   797→
   798→// ✅ CORRECT - fail fast if not set
   799→const runtimeEnv = process.env['RUNTIME_ENVIRONMENT'];
   800→if (!runtimeEnv) {
   801→  console.error('[service-name] RUNTIME_ENVIRONMENT is required');
   802→  process.exit(1);
   803→}
   804→
   805→// ✅ CORRECT - use requireEnv helper that throws
   806→const apiUri = requireEnv('API_URI_EXTERNAL');
   807→```
   808→
   809→**Why this matters:**
   810→
   811→1. **Production safety:** A misconfigured service silently running in `dev` mode in production could expose debug information, skip security checks, or behave unexpectedly.
   812→
   813→2. **Data safety:** Local development accidentally connecting to production database (due to missing/wrong env file) could corrupt production data.
   814→
   815→3. **Fail fast:** If .env files are incomplete, the service should fail to start immediately with a clear error message, not silently run with wrong defaults.
   816→
   817→4. **Explicit configuration:** Every environment must have a complete, explicitly configured .env file. No assumptions, no magic defaults.
   818→
   819→**Acceptable exceptions:**
   820→
   821→- `process.env['HOME']` - System path, not application config
   822→- Optional feature flags with documented defaults
   823→- Values explicitly marked as optional in the config type
   824→
   825→#### Due Diligence Checklist for Configuration Changes
   826→
   827→Before implementing any configuration:
   828→
   829→- [ ] Check if the value already exists in `RuntimeConfigValues`
   830→- [ ] Use standard naming if the value type is shared across packages
   831→- [ ] Prefix package-specific values appropriately
   832→- [ ] Determine if value belongs in .env or CLI args
   833→- [ ] Review `packages/cwc-configuration-helper/CLAUDE.md` for patterns
   834→- [ ] Examine how similar packages handle their configuration
   835→
   836→**Common mistake to avoid:**
   837→
   838→❌ "This is a configuration issue, not a code issue" - WRONG. Configuration values ARE in code.
   839→
   840→✅ When a config value needs to change or be added:
   841→1. Update `configuration.ts` with the new value
   842→2. Update the package's `config.types.ts` if adding a new property
   843→3. Update the package's `loadConfig.ts` to read the env var
   844→4. Regenerate .env files
   845→
   846→See `packages/cwc-configuration-helper/CLAUDE.md` for detailed documentation on the configuration system.
   847→
   848→## Development Process
   849→
   850→### Tool, Framework, Version selection
   851→
   852→- mainstream, widely accepted, and thoroughly tested & proven tools only
   853→- the desire is to use the latest stable versions of the various tools
   854→
   855→### Adopt a "roll-your-own" mentality
   856→
   857→- we want to minimize the number of unnecessary dependencies to avoid headaches when upgrading our core tech stack
   858→- when it makes sense, we will build our own components and utilities rather than relying on a 3rd party package
   859→
   860→### Code Review Workflow Patterns
   861→
   862→**CRITICAL: When the developer provides comprehensive code review feedback and requests step-by-step discussion.**
   863→
   864→#### Developer Should Continue Providing Comprehensive Feedback Lists
   865→
   866→**Encourage the developer to provide ALL feedback items in a single comprehensive list.** This is highly valuable because:
   867→
   868→- Gives full context about scope of changes
   869→- Allows identification of dependencies between issues
   870→- Helps spot patterns across multiple points
   871→- More efficient than addressing issues one at a time
   872→
   873→**Never discourage comprehensive feedback.** The issue is not the list size, but how Claude Code presents the response.
   874→
   875→#### Recognize Step-by-Step Request Signals
   876→
   877→When the developer says any of these phrases:
   878→
   879→- "review each of these in order step by step"
   880→- "discuss each point one by one"
   881→- "let's go through these one at a time"
   882→- "walk me through each item"
   883→
   884→**This is a request for ITERATIVE discussion, not a comprehensive dump of all analysis.**
   885→
   886→#### Step-by-Step Review Pattern (Default for Code Reviews)
   887→
   888→When developer provides comprehensive feedback with step-by-step request:
   889→
   890→**✅ Correct approach:**
   891→
   892→1. **Present ONLY Point 1** with:
   893→   - The developer's original feedback for that point
   894→   - Claude's analysis and thoughts
   895→   - Any clarifying questions needed
   896→   - Recommendation for what to do
   897→
   898→2. **Wait for developer response** and engage in discussion if needed
   899→
   900→3. **After Point 1 is resolved**, present Point 2 using same format
   901→
   902→4. **Continue iteratively** through all points
   903→
   904→5. **After all points discussed**, ask "Ready to implement?" and show summary of agreed changes
   905→
   906→**Message format for each point:**
   907→
   908→```markdown
   909→## Point N: [Topic Name]
   910→
   911→**Your Feedback:**
   912→[Quote the developer's original feedback for this point]
   913→
   914→**My Analysis:**
   915→[Thoughts on this specific point only]
   916→
   917→**Questions:** [If clarification needed]
   918→
   919→- Question 1?
   920→- Question 2?
   921→
   922→**Recommendation:**
   923→[What Claude thinks should be done]
   924→
   925→---
   926→
   927→_Waiting for your thoughts on Point N before moving to Point N+1._
   928→```
   929→
   930→**❌ What NOT to do:**
   931→
   932→- Present all 10-15 points with full analysis at once
   933→- Make the developer reference "Point 7" or scroll to find what they want to discuss
   934→- Skip the iterative conversation pattern when explicitly requested
   935→
   936→#### Alternative: Full Analysis First Pattern
   937→
   938→**Only use this pattern when developer explicitly requests it:**
   939→
   940→Developer says:
   941→
   942→- "Give me your analysis on all points first"
   943→- "Show me all your recommendations, then we'll discuss"
   944→- "I want to see the big picture before deciding"
   945→
   946→In this case:
   947→
   948→1. Present comprehensive analysis of all points
   949→2. Wait for developer to identify which points need discussion
   950→3. Focus conversation only on points developer has questions about
   951→
   952→#### Benefits of Step-by-Step Pattern
   953→
   954→- **Easy to follow:** Each message is focused on one decision
   955→- **Encourages discussion:** Natural to discuss one topic at a time
   956→- **No reference confusion:** No need to say "regarding Point 7..."
   957→- **Clear progress:** Both parties know exactly where we are in the review
   958→- **Better decisions:** Focused attention leads to better analysis
   959→
   960→#### Implementation Phase
   961→
   962→After all review points are discussed and decisions made:
   963→
   964→1. **Summarize all agreed changes** in a checklist format
   965→2. **Ask for explicit approval** to proceed: "Ready to implement these changes?"
   966→3. **Proceed with implementation** in logical groups
   967→4. **Update documentation** if patterns/learnings emerged during review
   968→
   969→**Session 010 Learning:** This pattern was established after Claude Code incorrectly presented all 14 review points at once despite clear request for step-by-step discussion. This made it difficult for the developer to engage in focused discussion on individual points.

   311→**Naming convention:** Prefix with package name when document is package-specific:
   312→- `cwc-api-implementation-checklist.md`
   313→- `cwc-website-specification-checklist.md`
   314→- `cwc-transcript-parser-tech-reference.md`
   315→
   316→**Rule:** When asked to create a checklist, specification, or planning document, place it in `./documents/`.
   317→
   318→### Technical Debt Tracking
   319→
   320→**Technical debt, future improvements, and enhancement ideas are tracked in `documents/cwc-tech-debt.md`.**
   321→
   322→During planning and development sessions, when improvements or enhancements are identified but deferred to avoid scope creep:
   323→
   324→1. **Capture the idea immediately** in `documents/cwc-tech-debt.md`
   325→2. **Include context** - session number, priority, effort level
   326→3. **Document current vs desired state** - what exists now, what should exist
   327→4. **Note the benefit** - why this matters
   328→
   329→**Examples of what to capture:**
   330→- Enhancements identified during planning (e.g., AI agent for sensitive data detection)
   331→- Better long-term solutions when implementing quick fixes
   332→- Patterns that could be improved across the codebase
   333→- Performance optimizations identified but not yet implemented
   334→
   335→**This prevents scope creep** while preserving valuable insights for future development work.
